1940 United States presidential election in Arkansas

The 1940 United States presidential election in Arkansas took place on November 5, 1940, as part of the 1940 United States presidential election. State voters chose nine representatives, or electors, to the Electoral College, who voted for president and vice president.

Except for the Unionist Ozark counties of Newton and Searcy where Republicans controlled local government, Arkansas since the end of Reconstruction had been a classic one-party Democratic “Solid South” state. Disfranchisement of effectively all Negroes and most poor whites by a poll tax since 1890 meant that outside those two aberrant counties, the Republican Party was completely moribund and Democratic primaries the only competitive elections.

Increased voting by poor Ozark whites as a protest against Woodrow Wilson's internationalist foreign policy meant that Warren G. Harding in 1920 was able to win almost forty percent of the statewide vote; and 1928 saw the rest of the Outer South and North Alabama bolt the anti-Prohibition Catholic Al Smith. However, the presence of Arkansas Senator Joseph Taylor Robinson as running mate meant that within Arkansas only the most northwesterly counties with ordinarily substantial Republican votes suffered the same fate.

The following years saw Arkansas plunge into the Great Depression, followed almost immediately by a major drought from the summer of 1930s until the winter of 1931 and 1932. Like in the rest of the "Solid South", Arkansas gave overwhelming support to Democrat Franklin D. Roosevelt in 1932, with Roosevelt carrying every county in the state. His popularity would lessen somewhat during his second term due to the urban and labor bias of the New Deal, but Roosevelt remained in no danger in 1940. This was especially true given that the South had never experienced German or Scandinavian immigration and thus strongly sympathized – as FDR did – with Britain in World War II. Thus FDR was able to almost maintain his 1936 majority in Arkansas, and replicated the county map of 1896, 1916, 1924 and 1936. As of 2020, this remains the last time that a presidential nominee has won more than seventy percent of the vote in Arkansas.
