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.
Legacy of the Free Soil Party. The Compromise of 1850 was assumed, for a time, to have settled the issue of slavery. And thus the Free Soil Party faded away. The party nominated a candidate for president in 1852, John P. Hale, a senator from New Hampshire. But Hale only received about 150,000 votes nationwide and the Free Soil Party was not a factor in the election.
