After the abolition of the BEW, speculation began as to whether Roosevelt would drop Wallace from the ticket in the 1944 election. Gallup polling published in March 1944 showed that Wallace was clearly the most popular choice for vice president among Democrats, and many journalists predicted that he would win renomination. As Roosevelt was in declining health, party leaders expected that the party's vice-presidential nominee would eventually succeed Roosevelt, and Wallace's many enemies within the Democratic Party organized to ensure his removal. 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 wrote, "I personally would vote for [Wallace's] renomination if I were a delegate to the convention".
