What about Franklin Pierce?
"nominated for president as a dark horse candidate on the 49th ballot at the 1852 Democratic National Convention. In the presidential election, Pierce and his running mate William R. King won in a landslide,"
I'm wrong, I read that somewhere but didn't check facts, shame on me.
Pierce was a Democrat; he only won because the Whig Party was in the process of breaking up over the issue of the extension of slavery to territories.
Sounds good. Let's stick with the Kings again--how about the man that Ann Coulter calls the best man in DC--Congressman Steve King from Iowa. (He's a closet Freeper)
