Two years later , in 1952 , Miller was one of the few California Democratic office-holders to become an early supporter of Tennessee Senator Estes Kefauver 's campaign for the presidency . The regular Party organization had originally supported the re-election of President Harry Truman , but when Truman withdrew from the race , the Party professionals , in desperation , coalesced around Pat Brown as their " favorite son " . In the June Primary , Kefauver easily defeated the Brown slate and the winning California delegation to the 1952 Democratic National Convention , largely composed of Kefauver supporters , chose Miller as delegation chairman . Kefauver later lost the Convention nomination to Illinois Governor Adlai Stevenson , a late entry into the race , but that fall , both the Truman professionals and the Kefauver and Stevenson amateurs at last united in selecting Miller as the new Chairman of the state Democratic Party
