Who would in a fight between Batman, Superman, and Ron Paul?
If I may interject here, aside from the fact that Ron Paul is Batman, Batman would most assuredly win. Last I read, he has the only supply of Kryptonite left on earth stored in his batcave. If you've read Frank Millers "The Dark Knight Returns" and "The Dark Knight Strikes Back", the Dark Knight manhandles the Last Son of Krypton more than competently. In the "Batman: Hush: mini-series, Batman is able to delay his Kryptonian adversary using merely his own resourcefulness and but one ring of Kryptonite. Imagine what a fully armed Batman would be capable of against the Godless alien.
EDIT: I'd also like to note the scene in "Superman: Red Son" (or whatever that mini-series was), that Batman, again, outsmarts the Big Blue Boyscout.
