I have no problem admitting both Bush's have screwed up in some ways, however if you look at what was happening when Bush Sr was running against Clinton he was closing the gap to within 2 or 3 percentage points and probably would have won until the papers printed their stories, (Ill find a link to that) three days before the election, then printed retractions afterwards on the back pages. I don't think it was smart for Bush Sr to raise taxes for many reasons, politically it was his thorn and the Dems golden nugget., but still he came very close to winning even with that "Read my lips" broken pledge. I remember this well as I worked on that campaign.
Btw Im not a Republican, Im a conservative independant.
