It's nice that you chose such an "unbiased" website for your "evidence."
However I disagree with most of these "worst moments." In fact, many of those, primarily limiting stem cell research and abandoning the Kyoto protocol, I believe that President Bush should be commended for. I'm against embryonic stem cell research and I don't think we need to be putting ourselves under the thumb of the UN for this myth called "global warming."
I also believe that the tax cuts for the wealthy are a good thing and I disagree that it ties in with the economic crash at all.
Also, they weren't torturing anybody. I don't buy this new liberal kick that these "enhanced interrogation tactics" are torture. I think that's purely a political ploy and has nothing to do with our values as Americans.
However, most of that stuff can just be chalked up to hindsight being 20/20. It's easy to look back to the past and think "well they should have done this and this." Especially anything concerning Hurricane Katrina and 9/11.
Some of those are mistakes, but not big ones unless you're predisposed to hate Bush. My list of Bush's greatest mistakes would be two:
1. Forcing Israel to give land to the terrorist organization known as "The Palestinian People."
2. the bank bailout last October
However, just because I disagree with him on these issues doesn't mean that I think he did a terrible job. He kept our country safe from terror for 7 years, deposed a brutal dictator, freed an entire nation, and forced the world's top terrorist organizations back underground. That's success in my book and I think history will reflect that.
