 Although labor leaders had backed Chandler's gubernatorial bid, they endorsed Barkley because of Roosevelt's support for labor unions.After the congressional session, Barkley resumed his "Iron Man" campaign style, making between 8 and 15 speeches each day and traveling, on average, per week.This countered Chandler's implication that Barkley's age was a disadvantage, a charge that was further blunted when the younger Chandler fell ill in July, temporarily halting his campaigning.
