From 1789 to 1913, when the Seventeenth Amendment to the U.S. Constitution was ratified, senators were elected by state legislatures. Beginning with the 1914 general election, all U.S. senators have been chosen by direct popular election. The Seventeenth Amendment also provided for the appointment of senators to fill vacancies.
There have been many landmark contests, such as the election of Hiram Revels, the first African American senator, in 1870. In 1932 Hattie Caraway of Arkansas became the first woman elected to the Senate. In 1948, when Margaret Chase Smith was elected to the Senate, she became the first woman to serve in both houses of Congress. In her 1960 bid for reelection, Smith made history again when she defeated Lucia Cormier. Senators have been elected by write-in votes and some have seen their elections contested. There have been landslide elections, while others were decided by the slimmest of margins.
Senators have often played key roles in presidential elections. Since 1789 sixteen senators have become president, but only three have gone directly from the Senate to the White House. In 1837 the Senate fulfilled its constitutional duty to break a deadlock and select a vice president from among the top contenders, electing Richard M. Johnson as vice president.
Unusual circumstances also have produced some unique elections. In 1861, for example, in the midst of the Civil War, a pro-Union faction within the seceded state of Virginia created its own government and elected its own U.S. senators.
Since the first elections in 1788, 1,931 men and women have served in the United States Senate.
