Dewey's campaign team originally wanted Illinois Governor Dwight Green to be his running mate, but the opposition of Colonel Robert R. McCormick, the powerful publisher of the "Chicago Tribune", nixed his chances. According to journalist Jules Abels, Dewey managers Brownell, Sprague, and Jaeckle then appeared to offer the vice-presidential nomination to influential Indiana Congressman Charles Halleck, in exchange for Halleck delivering the entire Indiana delegation to Dewey. Halleck did so, but Dewey, who had not been present at the meeting between his managers and Halleck, decided to reject his candidacy, telling his aides "Halleck won't do." After Dewey told Halleck of his decision, Halleck "was first speechless with disbelief and then overcome with emotion." He told Dewey that "you're running out on the Eightieth Congress, and you'll be sorry!" Abels wrote that Dewey's decision to deny Halleck the vice-presidential bid "may have been a fateful one...Halleck with his forceful personality might have changed the tone of the Dewey campaign, and certainly the issue of the record of the GOP-controlled Eightieth Congress would have to have been met heads on." Instead, Dewey chose popular governor (and future Chief Justice) Earl Warren of California as his running mate. Following the convention, most political experts in the news media rated the Republican ticket as an almost-certain winner over the Democrats.
