"According to his campain, because he is consistent and he doesn't send "mixed messages"." I agree with John Stewart in his interview with Bill O'Reilly last night... Bush would rather be sure of something than right about it.
It just goes to show, with enough fear, and repetition, people will stand behind anything.
As far as the invasion of Afghanistan, It is getting pretty old when people reference that as some of Bush's outstanding record. A couple of planes killed thousands of people. The person that organized it was in Afghanistan. We said hand him over, they said no. We invaded. Bush didn't take any radical steps in that decision, he did not do anything extraordinary. He made a decision that my five year old could have made. Then, instead of hunting down the leader (as Bush promised he would at all costs before later stating that He didn't care where Bin Laden was, and that it was not a priority) he starts another war, in an unrelated country under false pretenses, and bad info, thus spreading our military thinner.
