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.
Democrats -- General Lewis Cass (believed in popular sovereignty) The Whigs -- Zachary Taylor The Free Soil Party -- Martin Van Buren (a former president who condemned slavery) Why Important? Neither the Democrats or the Whigs wanted to discuss slavery, so the Free Soil Party formed and ran Van Buren.
