America's Most Bigoted President?

Wow, that's a tough one but I'm probably going to have to go with Millard Fillmore. As President, he strongly supported slavery into the territories and was also one of the major drivers of the Fugitive Slave Act....And his bigotry didn't end when he left the Presidency (it was actually just getting started) in that he was one of the "founding fathers" of the Know Nothing movement of the 1850s that was virulently anti-Irish, virulently anti-German, and virulently anti-Catholic, and which also essentially advocated an end to all immigration (except of course from England). I mean, I know that it's a hard thing to vote against a dude like Andrew Jackson who was a) one of the largest slave-owners in the entire Southeast and b) a practitioner of ethnic cleansing pertaining to the Native-Americans (or even a Woodrow Wilson who advocated eugenics and segregated the federal work force and U.S. military) but at least for now I'm probably going to stick with old Millard.......That, and doesn't he kind of look like Alec Baldwin?
