I've always been partial to Michael Dukakis, mostly because of his eyebrows, but also because he inspired Regan to say: "I think I was kidding, but I don't think I should have said what I said."
I also like Gore not for his personality or politics, but his "I AM THE PRESIDENT, DAMN IT, AND I AM GOING TO EAT LIKE THE PRESIDENT!" weight gain in 2000.
