1848 election: polk decided not to run for a second term, as he gained little support/credit for the mexican war. Democrats nominated 'crass' around the idea of popular sovereignty.
1848 election: Whigs nominated war hero 'taylor' , was a slave owner. In north campaigned for 'anti slavery' and south used 'southern rights' (why they won).
1848 election: free soil party was formed of some northern democrats, whigs who didn't want to support a slave owner, liberty party - the party supported the wilmot proviso.
1848 election: taylor and the whigs won.
There was tension in congress - ideas around popular soveringty, wilmot and calhoun were consistently debated.
California (has gold rush) and new mexico (has mormons) - previously owned by mexico, gained in mexican war. Both want to join the union eventually. Main issue was slavery, previously it was not.
President Taylor is seen as: honest, an amateur and a slave owner. He shunned advice of henry clay (a slave owning whig, known for compromise) and others, in favor of a more radical 'Seward'. He was anti slavery.
In an attempt to act quickly, Taylor encouraged california/new mexico apply to the union quickly. He was certain they would both vote free. Taylor didnt want to abolish slavery, but also didnt want to rekindle the issue.
Taylors actions: california then applied as a free state. But new mexico had a boundary dispute with texas. North (and taylor) supported new mexico and South supported texas. Clash between texan and US armies seemed imminent.
Southern Resentment: south believed neither california/new mexico should be admitted without southern compensation. Led to nashville convention. Divisions were reflected in congress and senators were having fistfights.
Southern Resentement: North were ignoring the fugitive slave act of 1793 which said slaves who fled should be returned to their owners.
