Not to put President Bush down, but how many of his promises were just campaign year politics? If you go back and look at every election from 2000 on back, most candidates promised many things that in retrospect, they knew they had no chance of implementing. He can't even be faulted if he was makings promises he knew couldn't happen, because that has become an accepted part of the way campaigns are.
I don't think your criticism applies to President Bush. He campaigned in 2000 on tax cuts and education reforms, and got both through Congress despite the fact that he did not even have a plurality of the votes.
