The Whig Party was in the process of disintegrating. The radical anti-slavery Whigs formed the Anti-Nebraska Party, the moderate anti-slavery wing became the Republican Party in other States, but still retained the Whig label in New York. Most of the Whigs which favored a compromise, or preferred to sidestep the issue, joined the Know Nothing movement which ran as the Native American Party.
