- Long had now earned a reputation, as Williams reports, as "a leading member of the progressive bloc in the Senate." In the presidential election of 1932, Long became a vocal supporter of the candidacy of Franklin Delano Roosevelt. He believed Roosevelt to be the only candidate willing and able to carry out the drastic redistribution of wealth that Long believed was necessary to end the Great Depression. At the Democratic National Convention, Long was instrumental in keeping the delegations of several wavering states in the Roosevelt camp. Long expected to be featured prominently in Roosevelt's campaign, but he was disappointed with a speaking tour limited to four Midwestern states.
Long managed to find other venues for his populist message. He campaigned to elect Senator Hattie Caraway of Arkansas, the underdog candidate in a crowded field, to her first full term in the Senate by conducting a whirlwind, seven-day tour of that state. (Caraway had been appointed to the seat after her husband's death.) He raised his national prominence and defeated by a landslide the candidate backed by Senator Robinson. With Long's help, Caraway became the first woman elected to the U.S. Senate. Caraway told Long, however, that she would continue to use independent judgment and not allow him to dictate how she would vote on Senate bills. She also insisted that he stop attacking Robinson while he was in Arkansas.
