The 1932 United States Senate election in Iowa took place on November 8, 1932. Incumbent Republican Senator Smith Brookhart, a controversial progressive figure within the conservative Iowa Republican Party, was defeated in the June Republican primary by Henry A. Field. Field was in turn defeated in the general election by Democrat Louis Murphy. Brookhart also entered the general election as the candidate of the Progressive Party but finished a distant third. Primary elections were held on June 6. Field defeated Brookhart in the Republican primary, and Murphy defeated a four-man Democratic field including former Senator Daniel F. Steck and future Governor Nelson G. Kraschel. Murphy's victory made him just the second Democratic Senator from Iowa elected since 1858 and the first to win election directly. Background Senator Smith W. Brookhart was first elected to the Senate in 1922, winning a special election to succeed William S. Kenyon. After joining the Senate, Brookhart's "pugnacious cowhide radicalism nettled patrician Senators." His indifference to President Calvin Coolidge in the 1924 presidential election also upset conservatives. In 1924, he attempted to win re-election to a full term, and it initially appeared he had narrowly defeated Democratic nominee Daniel Steck despite the defection of many conservative Republicans. However, Steck challenged the result in the U.S. Senate and, during a lengthy process, the Iowa Republican Party sided with Steck. Brookhart was removed from office on April 12, 1926 and replaced with Steck by a vote of 45–41. A dozen Senate Republicans voted with Democrats to unseat Brookhart. Immediately upon his ouster from the Senate, Brookhart returned to Iowa and challenged the incumbent Republican Senator for Iowa's other Senate seat, Albert B. Cummins, a respected veteran of the Senate. Brookhart defeated Cummins in a landslide, despite having little time or resources to mount a campaign, and was returned to the Senate in the fall in another landslide victory.
