Women in the United States Senate

There have been 57 total women in the United States Senate since its establishment in 1789.[1] The first woman who served as a U.S. senator, Rebecca Latimer Felton, represented Georgia for a single day in 1922. The first woman elected to the Senate was Hattie Caraway from Arkansas in 1932. Seventeen of the women who have served were appointed; seven of those were appointed to succeed their deceased husbands. The 116th Congress has 26 female senators, meaning for the first time in history, one-fourth of the members of the U.S. Senate are female. Of the 57 women in the U.S. Senate, 36 have been Democrats and 21 have been Republicans.

History

One woman (Barbara Mikulski) was re-elected and four women were elected to the Senate in 1992, the "Year of the Woman", L-R: Patty Murray, Carol Moseley-Braun, Mikulski, Dianne Feinstein, Barbara Boxer.

Eight women Senators meet in 1997. Left to right: Patty Murray, Susan Collins, Olympia Snowe, Carol Moseley-Braun, Kay Bailey Hutchison, Barbara Mikulski, Mary Landrieu, and Dianne Feinstein.

By the 111th United States Congress (2009–2011), the number of women Senators had increased to 17, including 4 Republicans and 13 Democrats

For its first 130 years in existence, the Senate's membership was entirely male. Until 1920, few women ran for the Senate. Until the 1990s, very few were elected. This paucity of women was due to many factors, including the lack of women's suffrage in many states until ratification of the Nineteenth Amendment to the United States Constitution, women's limited access to higher education until the mid-1900s, public perceptions of gender roles, and barriers to women's advancement such as sex discrimination.

The first woman in the U.S. Senate was Rebecca Latimer Felton, who served representing Georgia for only one day in 1922. Hattie Caraway became the first woman to win election to the Senate (Arkansas), in 1932. Margaret Chase Smith was the first woman to serve in both the House and Senate; she first served in the House, and began serving in the Senate in 1949. Margaret Chase Smith won her 1960 race for Senate in the nation's first ever race pitting two women (her and Lucia Cormier) against each other for a Senate seat. Muriel Humphrey Brown was the first and only Second Lady to serve in the United States Senate. After her husband, Hubert Humphrey, was defeated in the 1968 presidential election, he won back his old Senate seat from Minnesota. Following his unexpected death in office, Brown was appointed by the Governor of Minnesota in 1978 to fill her late husband's Senate seat. She served for less than one year, and did not seek reelection.

In 1978, Nancy Kassebaum became the first woman ever elected to a full term in the Senate without her husband having previously served in Congress.[2] Since 1978, there has always been at least one woman in the Senate. The first woman to be elected to the Senate without any family connections was Paula Hawkins (R-FL), elected in 1980. There were still few women in the Senate near the end of the 20th century, long after women began to make up a significant portion of the membership of the House. The trend of few women in the Senate began to change in the wake of the Clarence Thomas Supreme Court nomination hearings, and the subsequent election of the 103rd United States Congress in 1992, which was dubbed the "Year of the Woman."[3] In addition to Barbara Mikulski, who was reelected that year (1992), four women were elected to the Senate, all Democrats. They were Patty Murray of Washington, Carol Moseley Braun of Illinois, and Dianne Feinstein and Barbara Boxer, both of California. Carol Moseley Braun, who was African-American, was the first woman of color in the Senate. She was also the first woman to defeat an incumbent senator, winning the 1992 Democratic primary election over Alan Dixon. Later in 1992, Dianne Feinstein was the first woman to defeat an incumbent senator from a different party when she defeated John Seymour in a special election. Feinstein entered the Senate the same year as the first female Jewish senator.[4][5][6]

Bathroom facilities for women in the Senate on the Senate Chamber level were first provided in 1992.[7] Women were not allowed to wear pants on the Senate floor until 1993.[8][9] In 1993, Senators Barbara Mikulski and Carol Moseley Braun wore pants onto the floor in defiance of the rule, and female support staff followed soon after, with the rule being amended later that year by Senate Sergeant-at-Arms Martha Pope to allow women to wear pants on the floor so long as they also wore a jacket.[8][9]

The first time two female senators from the same state served concurrently was beginning in 1993; Dianne Feinstein and Barbara Boxer (both D-CA) were both elected in 1992, with Feinstein taking office that same year (as the result of a special election) and Boxer taking office in 1993 until 2016 when Boxer retired and Feinstein was joined by Kamala Harris. In June 1993, Kay Bailey Hutchison won a special election in Texas, and joined Kassebaum as a fellow female Republican senator. These additions significantly diminished the popular perception of the Senate as an exclusive "boys' club." Since 1992, there has been at least one new woman elected to the Senate every two years with the exception of the 2004 cycle (Lisa Murkowski was elected for the first time in 2004, but had been appointed to the seat since 2002). Since 2004, at least two new women have been elected to the Senate every two years, with the exception of 2010, when Kelly Ayotte of New Hampshire was the only new woman elected to the Senate.

Olympia Snowe arrived in the Senate in 1995, having previously served in the House of Representatives and both houses of the Maine state legislature. She and later Debbie Stabenow of Michigan and Kyrsten Sinema of Arizona are the only women to have served in both houses of a state legislature and both houses of the federal legislature. In 2000, Stabenow and Maria Cantwell became the first women to defeat incumbent elected senators in a general election, unseating Senators Spencer Abraham and Slade Gorton respectively.[10] Hillary Clinton is the first and only First Lady to run for and/or to win a Senate seat. Clinton joined the Senate in 2001 and served until 2009 when she resigned to become the 67th United States Secretary of State under President Barack Obama, before becoming the first woman to receive a major party's nomination for president in 2016. She was replaced by Kirsten Gillibrand, who has been reelected three times and was herself a candidate for president in the 2020 Democratic Party presidential primaries.

In 2008, Kay Hagan became the first woman to unseat a female incumbent, Elizabeth Dole. Upon the opening of the 112th Congress in 2011, New Hampshire Democrat Jeanne Shaheen was joined by newly elected Republican Kelly Ayotte, making up the first Senate delegation of two women belonging to different parties. Barbara Mikulski became the longest-serving woman senator (and Congresswoman) in 2012; she retired in 2017 as still the longest-serving after serving for forty years.

In 2012, there was a second "Year of the Woman" with the election of five women and the reelection of six women. This beat the record of four new female Senators from 1992 and set the record of five new women and eleven female Senators in one Senate class. The five new women were Democrat Tammy Baldwin of Wisconsin, Republican Deb Fischer of Nebraska, Democrat Heidi Heitkamp of North Dakota, Democrat Mazie Hirono of Hawaii, and Democrat Elizabeth Warren of Massachusetts. The driving force behind the addition of four of the Senators elected was Patty Murray, herself elected in 1992, who led the Democratic Senatorial Campaign Committee to recruit Baldwin, Heitkamp, Hirono, and Warren, along with several other competitive candidates. Hirono was the first Asian-American woman and first Buddhist person in the Senate, and Baldwin was the first openly gay person in the Senate. With 14 years of experience in the House of Representatives, Baldwin held the highest seniority of her entering class of senators in 2012.

Joni Ernst became the first female combat veteran to serve in the Senate when she joined in 2015. In 2016, a record 15 women were their party's nominee for Senate, 12 of whom were truly competitive. Louisiana also had a female senatorial candidate, but she did not make the run-off. Catherine Cortez Masto was among those elected in 2016; she was the first Latina Senator.[11] In a June 2016 primary election, as a result of California's recent establishment of the top-two primary, California Attorney General Kamala Harris and U.S. Representative Loretta Sanchez became the first women of the same party to advance to a Senate general election. In November 2016, Harris became the first woman to defeat a woman of the same party in a Senate general election. Jeanne Shaheen of New Hampshire and Maggie Hassan of New Hampshire hold the distinction of being the first and second women elected both governor and senator of a state; both served as Governor of New Hampshire and served together in the Senate starting in 2017.

In 2017 Tammy Duckworth became the first female double amputee in the U.S. Senate. On April 9, 2018, Duckworth gave birth to her daughter Maile Pearl, becoming the first incumbent Senator to give birth.[12] Shortly afterward, rules were changed so that a Senator has the right to bring a child under one year old on the Senate floor and breastfeed them during votes.[13] The day after those rules were changed, Maile became the first baby on the Senate floor when Duckworth brought her.[13][14]

In 2018 Kyrsten Sinema defeated Martha McSally to become Arizona's first female senator, and the first openly bisexual senator from any state. Two weeks later, Arizona Governor Doug Ducey announced that he would appoint McSally to Arizona's other Senate seat, which was becoming vacant with the resignation of Jon Kyl. Sinema and McSally are the only concurrently serving female senators to have previously faced off against each other in a Senate election.

Cumulatively, 36 female U.S. senators have been Democrats, while 21 have been Republicans. As of 2019, no female U.S. senator has ever died in office, won election to the House after her Senate term, resigned from a state governorship for the purpose of a Senate appointment by her successor, also won election as an independent or to represent more than one state in non-consecutive elections, served both seats of a state at different times, switched parties, or represented a third party in her career.

Some female U.S. senators have later run for U.S. president or vice president -- see list of female United States presidential and vice-presidential candidates.

As of January 2020, there are 26 women serving in the United States Senate, 17 Democrats and 9 Republicans, the highest proportion of women serving as U.S. senators in history.

In January 2017, the number of serving women Senators reached a record of 21, 16 of whom were Democrats, and the other 5 being Republicans. Democratic Senators Barbara Mikulski and Barbara Boxer did not seek reelection in 2016, while four new Democratic senators were elected: Catherine Cortez Masto (Nevada), Tammy Duckworth (Illinois), Kamala Harris (California), and Maggie Hassan (New Hampshire). Incumbent Republican Senator Kelly Ayotte (New Hampshire) lost to Hassan. Both of the seats that changed hands from Republican to Democrat were won by women (Duckworth and Hassan); this was also the case in the 2018 Senate election (Rosen and Sinema).

In January 2018, after the appointment of Democrat Tina Smith of Minnesota to the U.S. Senate to fill the vacancy created by the resignation of Al Franken, and in April 2018 after the appointment of Republican Cindy Hyde-Smith of Mississippi to the U.S. Senate to fill the vacancy created by the resignation of Thad Cochran, the number of female Senators increased to 25, with 17 being Democrats and 8 being Republicans. In January 2020, Kelly Loeffler was appointed to the Senate from Georgia, increasing the number of women in the Senate to 26.

Currently, six states (Arizona, California, Minnesota, Nevada, New Hampshire and Washington) are represented by 2 women to the U.S. Senate. Eleven current female senators had previously served in the U.S. House of Representatives—a distinction long held by only Margaret Chase Smith—Senators Stabenow, Cantwell, Gillibrand, Baldwin, Hirono, Capito, Duckworth, Blackburn, Rosen, McSally, and Sinema.

Election, selection and family

Before 2001, a plurality of women joined the U.S. Senate through appointment following the death or resignation of a husband or father who previously held the seat. An example is Muriel Humphrey (D-MN), the widow of former senator and Vice President Hubert Humphrey; she was appointed to fill his seat until a special election was held (in which she did not run). However, with the election of three women in 2000, the balance shifted; more women have now entered service as a senator by winning elections than by being appointed.

Recent examples of selection include Jean Carnahan and Lisa Murkowski. In 2000, Jean Carnahan (D-MO) was appointed to fill the Senate seat won by her recently deceased husband, Mel Carnahan. Carnahan—even though dead—defeated the incumbent senator, John Ashcroft. Carnahan's widow was named to fill his seat by Missouri Governor Roger Wilson until a special election was held. However, she lost the subsequent 2002 election to fill out the rest of the six-year term. In 2002, Lisa Murkowski (R-AK) was appointed by her father Alaska Governor Frank Murkowski, who had resigned from the Senate to become governor, to serve the remaining two years of his term. Lisa Murkowski defeated former governor Tony Knowles in her retention bid in 2004.

Two recent members of the Senate brought with them a combination of name recognition resulting from the political careers of their famous husbands and their own substantial experience in public affairs. The first, former senator Elizabeth Dole (R-NC), is married to former Senate Majority Leader and 1996 Republican presidential candidate Bob Dole and served as Secretary of Transportation under President Ronald Reagan and Secretary of Labor under President George H. W. Bush; she later ran a losing bid for the Republican presidential nomination in 2000. The other, former senator Hillary Clinton (D-NY), wife of former President Bill Clinton, was First Lady of the United States and First Lady of Arkansas before taking her seat in 2000. She too ran an unsuccessful campaign for her party's presidential nomination in 2008; she resigned in 2009 to become the secretary of state for the eventual victor of that election, Barack Obama. In 2016, she ran a successful campaign for her party's presidential nomination, eventually losing in the general election to Republican nominee Donald Trump.

Another famous name is Nancy Landon Kassebaum, the daughter of former Kansas governor and one-time presidential candidate Alf Landon. After retiring from the Senate, she married former senator Howard Baker (R-TN). Kassebaum has the distinction of being the first female elected senator who did not succeed her husband in Congress (Margaret Chase Smith was only elected to the Senate after succeeding her husband to his House seat). At the time of her retirement in 1997, Kassebaum was the second longest serving female senator, after Smith (Since 1997 five women have had Senate careers longer than Kassebaum's).

Firsts and onlies

The first woman in the Senate was Rebecca Latimer Felton, who served representing Georgia for only one day in 1922.

Hattie Caraway became the first woman to win election to the Senate (Arkansas), in 1932. Senator Margaret Chase Smith was the first woman to serve in both the House and Senate (she first served in the House, and began serving in the Senate in 1949), and she also won a 1960 race for Senate which was the nation's first ever race pitting two women (herself and Lucia Cormier) against each other for a Senate seat.

In 1978, Nancy Kassebaum became the first woman ever elected to a full term in the Senate without her husband having previously served in Congress.[15] Muriel Humphrey Brown was the first and only Second Lady to serve in the United States Senate. After her husband, Hubert Humphrey, was defeated in the 1968 presidential election, he ran for his old Senate seat from Minnesota. Following his death, Brown was appointed by the Governor of Minnesota in 1978 to fill her late husband's Senate seat. She served for less than one year, and did not seek reelection.

The first woman to be elected to the Senate without any family connections was Paula Hawkins, elected in 1980. She was also the first and to date only female member of The Church of Jesus Christ of Latter-day Saints elected to the United States senate. In 1992, Dianne Feinstein was the first woman to defeat an incumbent senator from a different party when she defeated appointed Senator John Seymour in a special election. Feinstein entered the Senate in 1992 as the first female Jewish senator.[4][5][6]

The first time two female U.S. senators from the same state served concurrently was beginning in 1993; Dianne Feinstein and Barbara Boxer (both D-CA) were both elected in 1992, with Feinstein taking office that same year (as the result of a special election) and Boxer taking office in 1993 until 2016 when Boxer retired and Feinstein was joined by Kamala Harris. In 1993 Carol Moseley Braun, who was African-American and had been elected the previous year, became the first woman of color in the Senate. She was also the first woman to defeat an incumbent senator, having toppled Senator Alan Dixon in the Democratic primary in 1992. Olympia Snowe arrived in the Senate in 1995, having previously served in the House of Representatives and both houses of the Maine state legislature. She and later Debbie Stabenow of Michigan and Kyrsten Sinema of Arizona are the only women to have served in both houses of a state legislature and both houses of the federal legislature. Susan Collins was elected in 1996 joining Olympia Snowe in representing Maine. This marked the first time a state was represented by two Republican women.

In 2000, Stabenow and Maria Cantwell became the first women to defeat incumbent elected senators in a general election, unseating Senators Spencer Abraham and Slade Gorton respectively. Hillary Clinton was the first and only First Lady to run for and win a United States Senate seat; she joined the Senate in 2001. She is also the only female U.S. senator (and only woman) to be the nominee of a major party for president of the United States, which occurred in 2016.

In 2008, Kay Hagan became the first woman to unseat a female incumbent, Elizabeth Dole. Upon the opening of the 112th Congress in 2011, New Hampshire Democrat Jeanne Shaheen was joined by newly elected Republican Kelly Ayotte, making the first female tandem senators that do not belong to the same party. Mazie Hirono, who joined the Senate in 2013, was the first Asian American woman and first Buddhist person in the Senate.

Tammy Baldwin, who joined the Senate in 2013, was the first and only openly gay person to serve in the United States Senate.[16] Joni Ernst became the first female combat veteran to serve in the Senate when she joined in 2015. In 2016, Kamala Harris was the first woman to defeat another woman from the same party, U.S. Representative Loretta Sanchez, in a general election. In 2017 Tammy Duckworth became the first female double amputee in the Senate and Catherine Cortez Masto joined the Senate as its first Latina.

Jeanne Shaheen of New Hampshire and Maggie Hassan of New Hampshire hold the distinction of being the first and second women elected both Governor and U.S. senator of a state; both served as Governor of New Hampshire and served together in the Senate starting in 2017. Tammy Duckworth became the first woman to give birth while holding a senate seat in the United States in 2018. Duckworth gave birth to Maile Pearl on April 9, 2018.[12] Shortly afterward, rules were changed so that a Senator has the right to bring a child under one year old on the Senate floor and breastfeed them during votes.[13] The day after those rules were changed, Maile became the first baby on the Senate floor when Duckworth brought her.[13][14]

Kamala Harris of California is the first woman senator to be a vice presidential nominee.

Notes

1. Abel resigned 3 days before the end of her term, a common practice to give her successor seniority advantage.
2. Predecessor resigned early to give successor seniority advantage, so the senator was appointed for the few days prior to the commencement of the elected term
3. When Kay Hagan defeated Elizabeth Dole, it was the first time in history a woman candidate defeated an incumbent woman.

2. Of the female Senators who preceded Kassebaum: Rebecca Latimer Felton, Rose McConnell Long, Dixie Bibb Graves, Vera C. Bushfield, Eva Bowring, Elaine S. Edwards, Muriel Humphrey, and Maryon Pittman Allen were all appointed and were never elected; Gladys Pyle (R-SD) and Hazel Abel (R-NE), were elected, but not to full terms (i.e., to complete terms where the previous senator had died or resigned, not to new six-year terms); Hattie Caraway and Maurine Brown Neuberger were both elected to full six-year terms, but their husbands had held the seat previously. Margaret Chase Smith's (R-ME) husband never served in the Senate, but he did serve in the House. When he died, Margaret won the ensuing election. Of the appointed senators, Long, Bushfield, Humphrey, and Allen were all appointed to fill out part of the terms of their deceased husbands, while Graves and Edwards were appointed by their husbands, the Governor of their states at the time. However, Kassebaum's father means that the first woman to be elected without any family connections was Paula Hawkins, elected in 1980.
