1928 United States presidential election in Indiana

A presidential election was held in Indiana on November 6, 1928, as part of the 1928 United States presidential election. The Republican ticket of the U.S. secretary of commerce Herbert Hoover and the senior U.S. senator from Kansas Charles Curtis defeated the Democratic ticket of the governor of New York Al Smith and the senior U.S. senator from Arkansas Joseph T. Robinson. Hoover defeated Smith in the national election with 444 electoral votes.

Indiana was seen as critical to Smith's chances in the national election; however, by early July, observers predicted that the opposition of the politically powerful Indiana Ku Klux Klan and the Anti-Saloon League would make it impossible for Smith to carry the state. Hoover blamed Democrats and the Federal Reserve System for the interwar farm crisis in a campaign visit to Indiana in late August, but the Indiana Farm Bureau did not endorse either ticket. Smith's Catholicism, opposition to Prohibition, and association with Tammany Hall alienated progressives who branded the candidate as a "patron of gambling and vice." Anti-Catholic dog whistles marked the Republican campaign in Indiana, leading Protestants across denominational lines to vote for Hoover. Hoover's national surrogates warned that Smith would "flood the nation with unsavory immigrants," create an epidemic of alcoholism, and open the path to state socialism. When Smith's train crossed into Indiana, he was greeted by a burning cross visible from the window of his car.
