Pierce, whose support had been slowly declining as the ballots passed, directed his supporters to break for Douglas, withdrawing his name in a last-ditch effort to defeat Buchanan. Douglas, only 43 years of age, believed that he could be nominated in 1860 if he let the older Buchanan win this time, and received assurances from Buchanan's managers that this would be the case. After two more deadlocked ballots, Douglas's managers withdrew his name, leaving Buchanan as the clear winner. To soften the blow to Pierce, the convention issued a resolution of "unqualified approbation" in praise of his administration and selected his ally, former Kentucky Representative John C. Breckinridge, as the vice-presidential nominee.[138][139][140] This loss marked the only time in U.S. history that an elected president who was an active candidate for reelection was not nominated by his political party for a second term.[note 6][141]
Pierce endorsed Buchanan, though the two remained distant; he hoped to resolve the Kansas situation by November to improve the Democrats' chances in the general election. He installed John W. Geary as territorial governor, who drew the ire of pro-slavery legislators.
