2020 United States Senate elections

The 2020 United States Senate elections will be held November 3, 2020,[1] with the 33 class 2 seats of the Senate being contested in regular elections.[2] The winners will be elected to six-year terms extending from January 3, 2021, to January 3, 2027.[3] There will also be two special elections: one in Arizona to fill the vacancy created by the death of John McCain in 2018 and one in Georgia following the resignation of Johnny Isakson at the end of 2019.[4][5]

In the 2014 United States Senate elections (the last regularly scheduled elections for class 2 Senate seats), the Republicans won nine seats from the Democrats and gained a majority in the Senate.[6] Republicans defended that majority in 2016[7] and 2018, and now hold 53 Senate seats. Democrats hold 45 seats, and independents caucusing with the Democratic Party hold two seats.[8]

Including the special elections in Arizona and Georgia, Republicans will be defending 23 seats in 2020, while the Democratic Party will be defending 12 seats.[9] Democrats will need to pick up three or four seats to gain a majority, depending on which party wins control of the vice presidency.[lower-alpha 1][10]

Change in composition

Republicans are defending 23 seats and Democrats 12.[9] Each block represents one of the 100 Senate seats. "D#" is a Democratic senator, "I#" is an Independent senator, and "R#" is a Republican senator. They are arranged so that the parties are separated and a majority is clear by crossing the middle.

Before the elections

Each block indicates an incumbent senator's actions going into the election. Both Independents caucus with the Democrats.

Predictions

Several sites and individuals publish predictions of competitive seats. These predictions look at factors such as the strength of the incumbent (if the incumbent is running for reelection) and the other candidates, and the state's partisan lean (reflected in part by the state's Cook Partisan Voting Index rating). The predictions assign ratings to each seat, indicating the predicted advantage that a party has in winning that seat.

Most election predictors use:

• "tossup": no advantage
• "tilt" (used by some predictors): advantage that is not quite as strong as "lean"
• "lean": slight advantage
• "likely" or "favored": significant, but surmountable, advantage
• "safe" or "solid": near-certain chance of victory

Alabama

Alabama election

Nominee Doug Jones Tommy Tuberville Party Democratic Republican

Incumbent U.S. senator Doug Jones Democratic

Main article: 2020 United States Senate election in Alabama

See also: List of United States senators from Alabama and 2020 United States House of Representatives elections in Alabama

Incumbent Democrat Doug Jones was elected in a special election in 2017, narrowly defeating Republican nominee Roy Moore. Jones is running for his first full term as a senator.[94][95]

Former Auburn University football head coach Tommy Tuberville defeated former senator and attorney general Jeff Sessions in a July 14 runoff to secure the Republican nomination. Sessions occupied the seat until 2017, when he resigned to become attorney general in the Trump administration.

Defeated in the March 3 Republican primary were 2017 Republican nominee Roy Moore, evangelist Stanley Adair,[96] Representative Bradley Byrne,[97] state representative Arnold Mooney,[98] and community activist Ruth Page Nelson.[99]

Alabama is one of the country's most Republican states and Jones's win was in part due to sexual assault allegations against Moore during the special election. Most analysts expect the seat to flip back to GOP control as Jones faces much stronger opposition from Tuberville. Despite some competitive polling, many in the Democratic establishment see Jones's seat as a lost cause, and he has struggled to raise money.[100]

Alaska

Alaska election

Nominee Dan Sullivan TBD Party Republican

Incumbent U.S. senator Dan Sullivan Republican

Main article: 2020 United States Senate election in Alaska

See also: List of United States senators from Alaska and 2020 United States House of Representatives election in Alaska

Republican Dan Sullivan was elected in 2014, defeating incumbent Democrat Mark Begich. He is running for a second term.[101]

Potential Democratic candidates include Begich, who was the Democratic nominee for governor of Alaska in 2018, and Anchorage mayor Ethan Berkowitz, who was the Democratic nominee for governor of Alaska in 2010. One Democrat, Edgar Blatchford, filed to run by the June 1 filing deadline.[53]

On July 2, 2019, Al Gross, an orthopedic surgeon and fisherman, declared his candidacy as an Independent.[102]

2020 United States Senate special election in Arizona

November 3, 2020

Nominee Martha McSally Mark Kelly Party Republican Democratic

Incumbent U.S. senator Martha McSally Republican

Republican senator John McCain was elected to a sixth term in 2016, but died in office in August 2018.[103] Republican governor Doug Ducey appointed former senator Jon Kyl to fill McCain's seat for the remainder of the 115th United States Congress.[104] After the end of the 115th Congress, Ducey appointed outgoing U.S. Representative and 2018 Republican Senate nominee Martha McSally as Kyl's successor for the 116th Congress.[105] McSally is running in the 2020 special election to fill the remainder of the term, which expires on January 3, 2023.[106]

Retired astronaut Mark Kelly is running for the Democratic nomination.[107]

Once a solidly Republican state, Arizona has trended more purple in recent years. Incumbent Republican Martha McSally was appointed to the late John McCain's seat two months after losing the 2018 Arizona U.S. Senate election to Democrat Kyrsten Sinema. Her Democratic opponent, astronaut Mark Kelly (who is married to former representative Gabrielle Giffords), has raised significantly more money and generally leads her by 5-15 points in polling. McSally is also suffering from low approval ratings due to her strong allegiance to Trump, who is unpopular in Arizona despite winning the state by 3.5 points in 2016.[108]

Arkansas

Arkansas election

Nominee Tom Cotton Ricky Harrington Jr. Party Republican Libertarian

Incumbent U.S. senator Tom Cotton Republican

Main article: 2020 United States Senate election in Arkansas

See also: List of United States senators from Arkansas and 2020 United States House of Representatives elections in Arkansas

Republican Tom Cotton was elected in 2014 after serving two years in the United States House of Representatives, defeating incumbent Democratic senator Mark Pryor by a comfortable margin. Cotton is seeking a second term.[109]

Joshua Mahony, a nonprofit executive and 2018 Democratic nominee for Congress in Arkansas's 3rd congressional district, filed to run for the Democratic nomination,[110] but dropped out just after the filing deadline.[111] No other Democrats filed within the filing deadline.

Christian missionary Ricky Dale Harrington, Jr., is running as a Libertarian,[112] and progressive activist Dan Whitfield is running as an independent.[113]

Colorado

Nominee Cory Gardner John Hickenlooper Party Republican Democratic

Incumbent U.S. senator Cory Gardner Republican

Main article: 2020 United States Senate election in Colorado

See also: List of United States senators from Colorado and 2020 United States House of Representatives elections in Colorado

Republican Cory Gardner was elected in 2014 after serving four years in the United States House of Representatives, narrowly defeating one-term Democrat Mark Udall. Gardner is seeking a second term.[114]

Former Colorado governor John Hickenlooper is the Democratic nominee, and generally leads Gardner by 10-20 points in the polls, with many pundits already considering him a favorite to win. Gardner is Colorado's only Republican statewide officeholder, and the once purple state has trended increasingly Democratic since Gardner's narrow win in 2014. Gardner also has low approval ratings due to his strong allegiance to President Donald Trump, who is unpopular in Colorado. Hickenlooper has also raised significantly more money than Gardner.[115]

Delaware

Main article: 2020 United States Senate election in Delaware

See also: List of United States senators from Delaware and 2020 United States House of Representatives election in Delaware

Democrat Chris Coons was reelected in 2014; Coons first took office after winning a 2010 special election, which occurred after longtime senator Joe Biden resigned to become vice president of the United States.

Conservative activist Lauren Witzke and attorney Jim DeMartino are running for the Republican nomination.

Georgia

See also: List of United States senators from Georgia and 2020 United States House of Representatives elections in Georgia

Due to the resignation of Republican senator Johnny Isakson at the end of 2019, both of Georgia's seats will be up for election this year. While the state overall still leans Republican, increased support for Democrats in Atlanta's suburbs has made the state more competitive, with a close governor's race, multiple close U.S. House races, and many other close local office races resulting in Democratic gains in 2018. Both elections are seen as competitive.

Georgia (Regular)

Georgia regular election

Nominee David Perdue Jon Ossoff Party Republican Democratic

Incumbent U.S. senator David Perdue Republican

Main article: 2020 United States Senate election in Georgia

The incumbent of the regular election, Republican David Perdue, will face Jon Ossoff, who won name recognition after losing the most expensive House race in US history.

Republican David Perdue was elected in 2014. He is seeking a second term.[116]

Former Columbus mayor Teresa Tomlinson and[117] 2018 lieutenant governor nominee Sarah Riggs Amico[118] lost the Democratic nomination to former congressional candidate Jon Ossoff, a documentary film producer and investigative journalist.[119] (Other potential Democratic candidates who did not run included former state senator Jason Carter and state representative Scott Holcomb.[116]) Ossoff will face Perdue in November.

Georgia (Special)

Georgia special election

November 3, 2020

Nominee Kelly Loeffler Doug Collins Party Republican Republican   Nominee Matt Lieberman Raphael Warnock Party Democratic Democratic

Incumbent U.S. senator Kelly Loeffler Republican

Main article: 2020 United States Senate special election in Georgia

Three-term senator Johnny Isakson announced that he would resign from the Senate at the end of 2019, citing health concerns.[120] A "jungle primary" will be held November 3, 2020; a candidate earning a majority of votes cast will win, but if no candidate wins a majority, a runoff election between the top two finishers will be held January 5, 2021.[121] The winner of the special election will serve until the expiration of Isakson's term on January 3, 2023.

Georgia governor Brian Kemp appointed Republican Kelly Loeffler to the seat; Loeffler took office on January 6, 2020, and will compete in the November 2020 election.[122] Other Republicans running for the seat include Wayne Johnson, former chief operating officer of the Office of Federal Student Aid,[123] and four-term U.S. representative Doug Collins.[124]

Unlike the regular election, the special election is being conducted as a jungle primary: all candidates are listed on the same ballot regardless of party affiliation, and if no candidate gets more than 50% of the vote, the top two will advance to a runoff on January 5, 2021. As in the regular election, there is a crowded field of Democratic candidates, but there is also a bitter contest on the Republican side between incumbent Kelly Loeffler, a businesswoman appointed to the seat after Isakson's resignation, and Doug Collins, a well-known U.S. representative. Collins leads Loeffler in the polls due to allegations of insider trading against Loeffler.[125]

Democrats running for the seat include Raphael Warnock,[126][127] Matt Lieberman,[128] Ed Tarver,[129][130] and Richard Dien Winfield.[131]

Two-term Republican Jim Risch was easily reelected in 2014. On August 13, 2019, he announced that he would seek a third term.[132] Former gubernatorial nominee Paulette Jordan won the Democratic nomination in a primary against retired cop Jim Vandermaas.

Illinois

Illinois election

Nominee Dick Durbin Mark Curran Party Democratic Republican

Incumbent U.S. senator Dick Durbin Democratic

Main article: 2020 United States Senate election in Illinois

See also: List of United States senators from Illinois and 2020 United States House of Representatives elections in Illinois

Four-term Democrat Dick Durbin, the Senate minority whip, was reelected in 2014 and is seeking a fifth term.[133]

Mark Curran, who served as sheriff of Lake County from 2006 to 2018, won the Republican primary with 41.55% of the vote and will face Durbin in the general election.[134]

Antiwar activist Marilyn Jordan Lawlor[135] and state representative Anne Stava-Murray[136] were going to challenge Durbin in the Democratic primary, but both withdrew.[137][138]

Republicans who ran include businessman Casey Chlebek,[139] U.S. Navy veteran and former police officer Peggy Hubbard,[140] Vietnam War veteran, physician, and 2018 Democratic primary candidate for governor of Illinois Robert Marshall,[141][142] Omeed Memar,[143] a dermatologist convicted of health care fraud in 2018,[144] Preston Gabriel Nelson,[145] Dean Seppelfrick,[146] and Tom Tarter.[147]

Iowa

Iowa election

Nominee Joni Ernst Theresa Greenfield Party Republican Democratic

Incumbent U.S. senator Joni Ernst Republican

Main article: 2020 United States Senate election in Iowa

See also: List of United States senators from Iowa and 2020 United States House of Representatives elections in Iowa

Republican Joni Ernst was elected in 2014 after serving four years in the Iowa Senate. She is seeking a second term.[148]

Democrats in the primary included former vice-admiral Michael T. Franken, attorney Kimberly Graham and businessman Eddie Mauro. Real estate broker Theresa Greenfield won the nomination.

Ernst's popularity has dropped in the polls, allegedly due to support for Trump's trade tariffs that have impacted Iowa farmers. But Democrats have had a hard time winning statewide in Iowa in recent years, narrowly losing the governor's election in 2018. Trump won the state by 9 points in 2016 after Barack Obama carried it in both 2008 and 2012. Democrats do hold three of Iowa's four congressional seats, picking up two of them in 2018. Greenfield, a first-time candidate backed by the Democratic establishment, defeated admiral Michael Franken, attorney Kimberly Graham, and businessman Eddie Mauro in the primary. She and Ernst are polling neck-and-neck in the general election, but Greenfield lacks name recognition, despite raising more money than Ernst.[149]

Kansas

Kansas election

Nominee Roger Marshall Barbara Bollier Party Republican Democratic

Incumbent U.S. senator Pat Roberts Republican

Main article: 2020 United States Senate election in Kansas

See also: List of United States senators from Kansas and 2020 United States House of Representatives elections in Kansas

Four-term Republican Pat Roberts is retiring and will not run for reelection.

Former secretary of state Kris Kobach,[150] state Turnpike Authority chairman (and former Kansas City Chief defensive end) Dave Lindstrom,[151] U.S. representative Roger Marshall, plumber/businessman Bob Hamilton, Kansas Board of Education member Steve Roberts,[152] state senate president Susan Wagle, and Republican socialist Brian Matlock all announced their candidacies.[153] Wagle has since withdrawn.

Other potential candidates (who ultimately did not run) included state attorney general Derek Schmidt and wealthy businessman and former 2018 lieutenant governor nominee Wink Hartman.

Kansas state treasurer Jake LaTurner[154] previously sought the nomination, but announced on September 3, 2019, that he would drop out of the Senate race to run for the U.S. House of Representatives.[155]

There was considerable speculation about a Senate bid by Mike Pompeo (the United States secretary of state, former director of the Central Intelligence Agency, and former U.S. representative for Kansas's 4th congressional district), but he did not run.[156][157]

Among Democrats, former Republican turned Democratic state senator Barbara Bollier is running,[158] as is Robert Tillman, nominee for Kansas's 4th congressional district in 2012 and candidate in 2016 and 2017.[159]

Former U.S. attorney Barry Grissom,[160] mayor of Manhattan Usha Reddi,[161] and former congresswoman Nancy Boyda[162] announced runs, but withdrew before the primary. Former governor Kathleen Sebelius declined to run.

Marshall and Bollier won their primaries and will face off in the general election.[163]

Kentucky

Kentucky election

Nominee Mitch McConnell Amy McGrath Party Republican Democratic

Incumbent U.S. senator Mitch McConnell Republican

Main article: 2020 United States Senate election in Kentucky

See also: List of United States senators from Kentucky and 2020 United States House of Representatives elections in Kentucky

Six-term Republican and current Senate majority leader Mitch McConnell was reelected by a comfortable margin in 2014 and is seeking a seventh term.

Most pundits see this as a likely Republican hold due to McConnell's large amount of reelection campaign funds, but he is one of the country's most unpopular senators, and his Democratic opponent, former Marine fighter pilot Amy McGrath, has been a strong fundraiser and trails McConnell only by single digits in polling. McConnell has proven to be a tough campaigner, however, and Kentucky is one of the most Republican states in the country. Democrat Andy Beshear narrowly won the Kentucky governor's race in 2019, unseating a similarly unpopular Republican incumbent.[164]

Mary Ann Tobin filed papers to run for the U.S. Senate on January 10, 2020. She is the former Kentucky auditor of public accounts and a state legislator.[165]

Amy McGrath announced her candidacy on July 9, 2019.[166] She is a former Marine and Navy fighter pilot who ran unsuccessfully for Congress in 2018 against incumbent representative Andy Barr.

Charles Booker, a member of the Kentucky House of Representatives[167] and Kentucky's youngest black state lawmaker,[168] entered the Senate race on January 5, 2020.[169] In the weeks before the primary, Booker gained popularity among progressives in the United States after the killing of George Floyd. McGrath defeated him by less than 3 percentage points.

Other candidates for the Democratic nomination were Jimmy Ausbrooks, a mental health counselor;[170] Mike Broihier, farmer and former U.S. Marine;[171] Andrew Maynard,[172] John R. Sharpensteen[172] and local business owner Bennie J. Smith.[173] Other potential Democratic candidates included state representative Rocky Adkins.[174] Steven Cox, a registered pharmacy technician,[175] dropped out and endorsed Booker.[176]

Louisiana

Main article: 2020 United States Senate election in Louisiana

See also: List of United States senators from Louisiana and 2020 United States House of Representatives elections in Louisiana

Republican Bill Cassidy was elected in 2014 after serving six years in the United States House of Representatives, defeating three-term Democrat Mary Landrieu. He is running for re-election.[177] Multiple Democratic candidates are running, but the Democratic Senatorial Campaign Committee has endorsed Shreveport mayor Adrian Perkins.[178]

A Louisiana primary (a form of jungle primary) will be held November 3; if no candidate wins a majority of the vote in the primary, a runoff election will be held.

Maine

Maine election

Nominee Susan Collins Sara Gideon Party Republican Democratic

Incumbent U.S. senator Susan Collins Republican

Main article: 2020 United States Senate election in Maine

See also: List of United States senators from Maine and 2020 United States House of Representatives elections in Maine

Four-term Republican Susan Collins was reelected by a wide margin in 2014. She is seeking a fifth term.[179]

Democrats running included state House speaker Sara Gideon,[180] attorney Bre Kidman,[181] and activist and 2018 gubernatorial candidate Betsy Sweet.[182] Gideon won the nomination.

Collins is polling neck-and-neck with or slightly behind Gideon. She has never faced a competitive election during her 24 years in the Senate even though Maine leans Democratic, as she has projected a centrist image. But she faces growing unpopularity due to her increasingly conservative voting record and her votes to confirm Brett Kavanaugh to the Supreme Court and to acquit President Trump in his impeachment trial. Gideon raised over three times as much money as Collins in the first quarter of 2020.[183]

Massachusetts

Main article: 2020 United States Senate election in Massachusetts

Democrat Ed Markey was reelected in 2014; he won a 2013 special election to replace longtime incumbent John Kerry, who resigned to become U.S. secretary of state. He is running for a second term.[184]

Joe Kennedy III, four-term U.S. representative for Massachusetts's Fourth District and grandson of former U.S. senator and U.S. attorney general Robert F. Kennedy, is challenging Markey for the Democratic nomination.[185]

Noted conspiracy theorist Shiva Ayyadurai, an independent candidate for U.S. Senate in 2018, and attorney Kevin O'Connor are seeking the Republican nomination.[186][187]

Michigan

Michigan election

Nominee Gary Peters John James Party Democratic Republican

Incumbent U.S. senator Gary Peters Democratic

Main article: 2020 United States Senate election in Michigan

See also: List of United States senators from Michigan and 2020 United States House of Representatives elections in Michigan

Democrat Gary Peters was elected in 2014 after serving six years in the U.S. House of Representatives. He is seeking a second term.[188]

2018 Senate nominee John James won the Republican nomination.[189] He faced token opposition for the Republican nomination from perennial candidate Bob Carr.[190]

Michigan is one of the most competitive states in national elections. James came unexpectedly close to unseating Michigan's other Democratic senator, Debbie Stabenow, in 2018. Stabenow is a longtime senator whose name recognition Peters lacks, but Republicans are growing more unpopular in Michigan after the state narrowly voted for Trump in 2016, then switched back to Democrats in all statewide races in 2018. Peters generally leads James by 8-12 points in the polls.[191]

Minnesota

Nominee Tina Smith Jason Lewis Party Democratic Republican

Incumbent U.S. senator Tina Smith Democratic

Main article: 2020 United States Senate election in Minnesota

See also: List of United States senators from Minnesota and 2020 United States House of Representatives elections in Minnesota

Incumbent Democrat Tina Smith was appointed to the U.S. Senate to replace Al Franken in 2018 after serving as lieutenant governor, and won a special election later in 2018 to serve the remainder of Franken's term. On August 11, she won the Democratic nomination to serve a full term.[192]

Former congressman Jason Lewis is the Republican nominee, defeating minor candidates Cynthia Gail, John Berman, Bob Carney and James Reibestein in the primary election.[193]

Mississippi

Incumbent U.S. senator Cindy Hyde-Smith Republican

Main article: 2020 United States Senate election in Mississippi

See also: List of United States senators from Mississippi and 2020 United States House of Representatives elections in Mississippi

After seven-term Republican senator Thad Cochran resigned in April 2018, Republican governor Phil Bryant appointed state agriculture commissioner Cindy Hyde-Smith to succeed him until a special election could be held later in the year. Hyde-Smith won the November 2018 special election to fill the remainder of Cochran's term, which ends in January 2021. Hyde-Smith is running for a full term.[194] She was unopposed in the Republican primary.

Former U.S. secretary of agriculture and 2018 Senate candidate Mike Espy won the Democratic primary with 93.1% of the vote.[195]

Libertarian candidate Jimmy Edwards also made the general election ballot.

Montana

Montana election

Nominee Steve Daines Steve Bullock Party Republican Democratic

Incumbent U.S. senator Steve Daines Republican

Main article: 2020 United States Senate election in Montana

See also: List of United States senators from Montana and 2020 United States House of Representatives election in Montana

Republican Steve Daines was elected in 2014 after serving two years in the United States House of Representatives. He is seeking a second term.[196]

Daines was opposed (prior to his nomination) in the Republican primary by hardware store manager Daniel Larson and former Democratic speaker of the Montana House of Representatives John Driscoll.

Incumbent governor Steve Bullock won the Democratic nomination,[197] defeating nuclear engineer and U.S. Navy veteran John Mues.[198]

Libertarian and Green party candidates will also appear on the general election ballot.

Once seen as likely to remain in Republican hands, Daines's seat is now competitive due to Bullock's last-minute entry. Bullock leads Daines by single digits in the most recent polling and has also raised more money than Daines. But Montana is expected to be safely Republican in the presidential election, meaning that Bullock is relying on Montana's history of ticket splitting, as he did in 2016 when he was reelected to a second gubernatorial term by 4 points despite Trump winning the state by 20 points. Montana also reelected Jon Tester, a Democrat, to the Senate in 2018, by 4 points. Daines was elected to a first term by a comfortable margin in 2014.[199]

Nebraska

Republican Ben Sasse was elected in 2014 after serving as the president of Midland University. He is seeking a second term.[200]

Sasse defeated businessman and former Lancaster County Republican Party chair Matt Innis in the Republican primary with 75.2% of the vote.

Businessman and 2018 U.S. Senate candidate Chris Janicek won the Democratic primary with 30.7% of the vote, defeating six other candidates.

Libertarian candidate Gene Siadek will also appear on the general election ballot.

New Hampshire

Two-term Democrat Jeanne Shaheen was narrowly reelected in 2014. She is seeking a third term.[201]

Former U.S. Army brigadier general Donald C. Bolduc, perennial candidate Andy Martin, and attorney Corky Messner are running for the Republican nomination.[202][203][204]

Libertarian Justin O'Donnell will appear on the general election ballot.[205]

New Jersey

Incumbent U.S. senator Cory Booker Democratic

Main article: 2020 United States Senate election in New Jersey

See also: List of United States senators from New Jersey and 2020 United States House of Representatives elections in New Jersey

Democrat Cory Booker was reelected in 2014; he first took office by winning a 2013 special election after serving seven years as mayor of Newark. Booker sought his party's nomination for President of the United States in 2020. Although the state allows him to simultaneously run for both president and the Senate, Booker suspended his presidential campaign on January 13, 2020, and confirmed his intention to seek a second Senate term.[206]

Republican candidates included engineer Hirsh Singh, 2018 Independent U.S. Senate candidate Tricia Flanagan, 2018 independent U.S. Senate candidate Natalie Lynn Rivera and Eugene Anagnos. The party ultimately nominated pharmacist, Georgetown University law professor, and attorney Rik Mehta.

Green Party candidate Madelyn Hoffman and two independent candidates will also appear on the general election ballot.

New Jersey has not elected a Republican senator since 1972, and all pundits expect Booker to be easily reelected.

New Mexico

Two-term Democrat Tom Udall is the only incumbent Democratic U.S. senator retiring in 2020.[207]

U.S. representative Ben Ray Luján[208] was unopposed for the Democratic nomination.

Among Republicans, former U.S. Interior Department official Gavin Clarkson and executive director for the New Mexico Alliance for Life Elisa Martinez ran. They lost in the primary to former KRQE chief meteorologist Mark Ronchetti.[209][210][211]

Libertarian Bob Walsh will appear on the general election ballot.

North Carolina

North Carolina election

Nominee Thom Tillis Cal Cunningham Party Republican Democratic

Incumbent U.S. senator Thom Tillis Republican

Main article: 2020 United States Senate election in North Carolina

See also: List of United States senators from North Carolina and 2020 United States House of Representatives elections in North Carolina

Republican Thom Tillis was elected in 2014 after serving eight years in the state House of Representatives, narrowly defeating one-term Democrat Kay Hagan. He faced a primary challenge from three different candidates.

State senator Erica D. Smith, Mecklenburg County commissioner Trevor Fuller, and former state senator Cal Cunningham ran for the Democratic nomination.

On March 3, 2020, Tillis and Cunningham won their parties' primaries.[212]

The Libertarian Party and the Constitution Party have candidates on the general election ballot.

Tillis has grown unpopular among both centrist and conservative Republicans due to his inconsistent support of Trump. He also suffers from low name recognition, and North Carolina is trending more purple, electing a Democratic governor in 2016. Tillis will face Democrat Cal Cunningham in the general election. Cunningham leads slightly in the polls.[213]

Notes

1. Because the vice president of the United States has the power to break ties in the Senate, a Senate majority requires either 51 Senate seats without control of the vice presidency or 50 seats with control of the vice presidency. Thus, assuming that the two independents continue to caucus with the Senate Democratic Caucus and if Kamala Harris is elected vice president in the 2020 election, the Democrats will have to gain at least three seats to win a majority. If Mike Pence is reelected vice president, Democrats will have to gain at least four seats to win a majority.
2. The 2 independents, Bernie Sanders and Angus King, have caucused with the Democratic Party since joining the Senate.
3. The last elections for this group of senators were in 2014, except for those elected in a special election or who were appointed after the resignation or passing of a sitting senator, as noted.
4. Republican Jeff Sessions ran uncontested in 2014 and won with 97.3% of the vote, but resigned on February 8, 2017 to become United States Attorney General.
5. Republican John McCain won in 2016 with 53.7% of the vote, but died on August 25, 2018.
6. Republican Johnny Isakson won with 54.8% of the vote in 2016, but resigned on December 31, 2019, due to declining health.
7. Democrat Al Franken won with 53.2% of the vote in 2014, but resigned on January 2, 2018.
8. Republican Thad Cochran won with 59.9% of the vote in 2014, but resigned on April 1, 2018 due to declining health.
