The primaries were contested mainly by Manhattan District Attorney Thomas E. Dewey and Senators Robert A. Taft and Arthur Vandenberg, though only a few states' primaries featured two or more of these men.
By the start of the convention, only 300 of the 1,000 convention delegates had been pledged to a candidate, far fewer than was necessary to determine a victor. Estimates of delegate loyalty placed Dewey first, Taft second, and Wendell Willkie, an internationalist businessman, third. Late momentum following the escalation of World War II allowed Willkie to take the nomination on the sixth ballot at the convention.
