The 1932 United States Senate elections coincided with the Democrat Franklin D. Roosevelt's landslide victory over the incumbent Herbert Hoover in the presidential election. The 32 seats of Class 3 were contested in regular elections, and special elections were held to fill vacancies. Events of the election With the Hoover administration widely blamed for the Great Depression, Republicans lost twelve seats and control of the chamber to the Democrats, who won 28 of the 34 contested races (two Democratic incumbents, Duncan U. Fletcher of Florida and John H. Overton of Louisiana, were re-elected unopposed). Democrats gained another seat through an appointment in Nebraska, bringing their total number of seats up to 60.

Among the Republican incumbents defeated in 1932 were Senate Majority Leader James Watson and five-term Senator Reed Smoot, an author of the controversial Smoot-Hawley tariff. This was the first of four elections in which a Senate leader lost re-election, and the only time they were a Republican. This election marked the first time a woman was elected to the Senate, that being Hattie Caraway of Arkansas. As of 2024, this is the last time Democrats won a Senate election in Kansas.

This is also one of only five occasions where 10 or more Senate seats changed hands in an election, with the other occasions being in 1920, 1946, 1958, and 1980.

Arkansas

There were two elections for the same seat, due to the November 6, 1931 death of two-term Democrat Thaddeus H. Caraway.

Caraway's widow, Democrat Hattie Wyatt Caraway, was appointed November 13, 1931 to continue his term.

Arkansas (special)

Arkansas (regular)

In May 1932, Caraway surprised Arkansas politicians by announcing that she would run for a full term in the upcoming election, joining a field already crowded with prominent candidates who had assumed she would step aside. She told reporters, "The time has passed when a woman should be placed in a position and kept there only while someone else is being groomed for the job." When she was invited by Vice President Charles Curtis to preside over the Senate she took advantage of the situation to announce that she would run for reelection. Populist former Governor and Senator Huey Long of neighboring Louisiana traveled to Arkansas on a seven-day campaign swing on her behalf. She was the first female senator to preside over the body as well as the first to chair a committee (Senate Committee on Enrolled Bills). Lacking any significant political backing, Caraway accepted the offer of help from Long, whose efforts to limit incomes of the wealthy and increase aid to the poor she had supported. Long was also motivated by sympathy for the widow and his ambition to extend his influence into the home state of his party rival, Senator Joseph Robinson, who had been Al Smith's vice-presidential candidate in 1928. Bringing his colorful and flamboyant campaign style to Arkansas, Long stumped the state with Caraway for a week just before the Democratic primary. He helped her to amass nearly twice as many votes as her closest opponent.

Long effectively used a method to quiet crying babies at campaign stops in Arkansas to encourage voter interest: Mrs. Caraway would never forget nor cease to laugh over the plans we made for caring for obstreperous infants in the audience so that their mothers might listen to the speeches without the crowds being disturbed. I remember when I saw her notice one of our campaigners take charge of the first baby. The child began fretting and then began to cry. One of the young men accompanying us immediately gave it a drink of water. The child quieted for a bit and resumed a whimper, whereupon the same campaign worker handed the baby an all-day sucker, which it immediately grasped and soon fell asleep. Mrs. Caraway did not understand that it was a matter of design until it had been repeated several times.Huey Pierce Long Jr., Every Man a King: The Autobiography of Huey P. Long (New Orleans: National Book Club, Inc., 1933), pp. 313–314.

Caraway went on to win the general election in November, with the accompanying victory of Franklin D. Roosevelt as U.S. President.

Russell then won the September 14, 1932 Democratic primary over Representative Charles R. Crisp (nicknamed by Russell as "kilowatt Charlie" due to his links to the unpopular Georgia Power Company), 57.72% to 42.28%. Russell was then unopposed in the November 8, 1932 special election.
