Latest Pew poll puts Bush at 33%. Let's see..... 3 years left.... current rate of decline.... could he end up with a negative approval rating? That would change the space-time continuum of the universe and possibly end the existence of all matter. We must then, in order to save ourselves, make sure that at least one polled person always responds with a positive approval.
Oh, wait... I keep forgetting that there are millions of people in this country who go out of their way to not think for themselves. So I guess we owe thanks to the sheep-people of this once-upon-a-time democratic republic for keeping our universe stable. At least until the Apocalypse/Rapture currently scheduled (by those same people) for 2010 or so.
