I was writing a memo just now, I wrote an unique and I just stopped and looked at it and realized it was wrong. My whole world had been turned upside down. Then I found this explanation and all is right with the world.
Liberty Party (1840) wanted to abolish slavery; Free Soil Party (1848) wanted to keep slavery from expanding into Western territories; American Party (Know-Nothings in 1854 & 1856) wanted to reduce immigration (nativism); Constitutional Union Party (1860) wanted a compromise between the North & South.
Liberty Party. The staunchly anti slavery, anti annexation, party was short lived, but captured 62,000 votes, a small number, but enough some historians argue to effectively rob Henry Clay of electoral votes in New York and Michigan thereby handing Polk the Presidency in 1844. Annexation fight.
