Who's the most ridiculed POTUS of history?

I've never thought so. I mean, I guess it's hard to quantify, but that's different from being ambiguous. If someone asked you, "Who in your high school class did people make fun of the most," you might know right away who it would be, or there might be multiple contenders. Other people in your class might have different opinions, but that doesn't mean you all don't know what the question is, just that it's hard to measure.
