United States Presidential Election of 1848

Background. The election followed the Mexican–American War, which concluded in 1848. Zachary Taylor, a major general, gained popularity through victories at Palo Alto, Resaca de la Palma, and Buena Vista. These military successes established him as a national hero, setting the stage for his political candidacy despite his initial reluctance to enter politics.

Whig Nomination. The Whig Party nominated Zachary Taylor at their 1848 national convention, defeating Henry Clay and Winfield Scott. Although Taylor had unclear political tenets and initially refused the nomination, the party convinced him to lead the ticket. His opposition to the war conflicted with party stalwarts, but his popularity as a general secured the nomination.

Democratic Nomination. The Democratic National Convention nominated Senator Lewis Cass of Michigan after Martin Van Buren withdrew due to a platform dispute. Cass's advocacy for popular sovereignty alienated the anti-slavery wing of the party, causing a split. Cass had served in the Senate from 1845 to 1848 before resigning to run for president.
