Dubinsky ultimately left the Labor Party in 1944 after a dispute with Hillman over whether labor leaders in New York, such as Mike Quill, who either were members of the Communist Party or were seen as sympathetic to it, should be given any role in the ALP. When Hillman prevailed, Dubinsky and his allies left to form the Liberal Party. The ALP went on to endorse Henry Wallace in the 1948 presidential election, while the ILGWU campaigned energetically for Harry S. Truman, nearly bringing New York State into his column.
