 Much of the opposition to Wallace stemmed from his open denunciation of racial segregation in the South, but others were concerned by Wallace's unorthodox religious views and pro-Soviet statements.Shortly before the 1944 Democratic National Convention, party leaders such as Robert E. Hannegan and Edwin W. Pauley convinced Roosevelt to sign a document expressing support for either Associate Justice William O. Douglas or Senator Harry S. Truman for the vice presidential nomination.Nonetheless, Wallace got Roosevelt to send a public letter to the convention chairman in which he stated, "I personally would vote for [Wallace's] renomination if I were a delegate to the convention".
