The story
In 1844 Democrat James K. Polk, a former House speaker from Tennessee, defeated Whig leader Henry Clay by 170 electoral votes to 105. The popular vote was close, about 49.5 percent to 48 percent. New York decided it: Polk carried the state by roughly 5,000 votes, while James Birney of the antislavery Liberty Party won about 16,000 there, many of them from voters who might otherwise have chosen Clay.
Polk was the first 'dark horse' nominee, chosen on the ninth ballot after former President Martin Van Buren failed to win two-thirds of the Democratic convention, largely because he opposed annexing Texas. Texas, independent since 1836, wanted to join the United States, but as a slave state its admission threatened the balance between free and slave states. Polk embraced expansion, promising both Texas and all of Oregon, while Clay wavered. Outgoing President Tyler took Polk's win as a mandate, and Congress approved annexation by joint resolution in early 1845. As president, Polk settled Oregon with Britain and waged the Mexican-American War.
Why it mattered
- Led to the annexation of Texas and then the Mexican-American War.
- Drove expansion to the Pacific through the Oregon Treaty and the Mexican Cession.
- Showed that a small antislavery party could swing a national election.
