[Cicero]

Obama is a pit bull. Santorum is a poodle, Romney a Cocker Spaniel and Gingrich a fellow pit bull. Now which dog do you take to the fight?

Actually, never mind the others, I'd be more inclined to say that Obama is a hyena.

[Reily]

If Zero is a hyena, then Newt is a Cape Buffalo. Possibly outside of the Hippo the most dangerous animal in Africa.
