There was a cacophony of voices criticizing GWB, yours included I'm sure. I had problems with GWB, but they were pretty well represented, along with about 30,000 criticisms I didn't share.
If GWB had campaigned as Obama did on 'Change we can believe in,' and promised the things Obama has (no more no-bid contracts, for example), and then blatantly reneged on his promise, you would be at the forefront of people ridiculing him. Or do you honestly believe you'd be a Bush apologist, saying "...why now all of a sudden does this stuff matter?" I think everyone here knows you'd be at his throat.
