In the aftermath of the Mexican–American War (1846–1848) and the Compromise of 1850, the Whig Party was torn over the issue of slavery. President Millard Fillmore, who had succeeded to the presidency in July 1850 after the death of President Zachary Taylor, had the strong backing of Southern Whigs. However, his enforcement of the Fugitive Slave Act of 1850 had alienated many Northern Whigs, who supported either Scott or Secretary of State Daniel Webster. Scott and Fillmore essentially tied on the first presidential ballot, while a smaller fraction of the vote went to Webster. There was little delegate movement over the next 46 ballots, but Scott gained momentum on the 48th ballot and clinched the nomination on the 53rd ballot.
