When the Democratic Party announced that Van Buren would be their vice presidential candidate, Floyd was not happy. He renewed his antagonism with Jackson accordingly. Floyd felt that Van Buren's would inject "Northern principles" into the government and would "lead with a rapidity of lightening to the sudden and immediate emancipation of slavery". Virginians led the movement to prevent Van Buren's election. Philip P. Barbour was brought forward as a running mate on a Jackson-Barbour ticket. "In this way Floyd expected to throw the choice of the vice-president into the Senate, where, it was thought, Van Buren's election could be prevented." As historian William J. Cooper noted, "For the Calhounites in Virginia, replacing Van Buren with Barbour would achieve two desired goals: eliminate the man they designated as the great enemy both of Calhoun and of the Virginia doctrine as well as symbolize the political resurgence of Virginia." Barbour, however, later withdrew his candidacy to accept Jackson's appointment as judge of the United States Circuit Court for the Eastern District of Virginia, and Van Buren became Vice President.
