President John Tyler's pursuit of Texas annexation divided both major parties by raising fears of expanding slavery and risking war with Mexico. Martin Van Buren's opposition to annexation cost him the Democratic nomination, while Henry Clay's repeated wavering on the issue undermined Whig cohesion. Tyler, expelled from the Whig Party, sought to use annexation as a political vehicle.
Held from November 1 to December 4, 1844, the election pitted Democratic nominee James K. Polk against Whig nominee Henry Clay. Polk united Northern expansionists seeking Oregon with Southern expansionists demanding Texas, running on a Manifest Destiny platform. He narrowly defeated Clay in the popular vote, with Liberty Party candidate James G. Birney's showing in New York proving decisive.
Following Polk's victory, Tyler proceeded to annex Texas, which became the proximate cause of the Mexican–American War during Polk's presidency. The election also marked the first time a third-party candidate demonstrably altered a U.S. presidential outcome, foreshadowing the growing influence of antislavery politics in subsequent decades.
Political Outcome
James K. Polk (Democrat) defeated Henry Clay (Whig) by a popular vote margin of 1.4%, winning the presidency and enabling Texas annexation.
