Well, I know who the anti-Christ is but I'm not saying either!   :-)
But it can't be GWB, unless he manages to rig this requirement sometime soon ...

...I saw that one of it's heads seemed to have a fatal wound but that this deadly injury had healed and, after that, the whole world had marveled and followed the beast ... they prostrated themselves in front of the beast, saying, "Who can compare with the beast?"

(Rev 13:3-5)

Far as I can see, George has only one head. Granted, that head's deficiencies are glaringly obvious and dangerous too, but not 'deadly' (at least for him). He's no Pied Piper! (although his inner circle does appear quite rat-infested). He's yet to be miraculously healed of anything. With the possible exception of a few million already-deluded bible-thumpers, he's far from becoming the object of the whole world's marvel or (willing) prostration. And he's certainly not beyond compare! Interesting parallels can be drawn with, for example, a garden slug (although slugs DO serve a few useful purposes). Perhaps a mad bull would be better?
