Input: Question: What states did Strom Thurmond win in 1948? Passage:In what is considered by most historians as the greatest upset in the history of American presidential politics, Democratic incumbent President Harry S. Truman defeated Republican nominee Thomas E. Dewey. Going into Election Day, virtually every prediction (with or without public opinion polls) indicated that Truman would lose. Truman took most states outside the Northeast and Deep South, and won the popular vote by four points. Dewey won his party's nomination for the second straight election, defeating Ohio Senator Robert A. Taft and former Minnesota Governor Harold Stassen on the Republican convention's second ballot. Truman won the Democratic nomination on the first ballot, but the party's platform on civil rights caused a third party run by Dixiecrat Strom Thurmond, the Governor of South Carolina. Thurmond took four states in the Deep South. Former Vice President and former Democrat Henry A. Wallace ran as the Progressive nominee, but took only two percent of the popular vote.
