I think it's pretty important to note that whether a politician's policies suck or not is a very subjective matter. While we may all agree (or in some cases, assume) that Bush's policies suck, they appealed to a lot of people on the mid-to-far-right scale. He is still a very revered politician in many people's eyes.

He may have twice swindled the American people into voting for him as President but those weren't the only elections he won. He was doing something right in enough people's eyes to get him into public office.
