do some people actually think that McCain will be a change from bush?

Obama holding on to small lead over McCain: poll
---
I'm glad that Obama has a lead, but how can it be a small lead?
I honestly don't understand how anyone could have lived through the last 8 years here in the United States and still even consider another repug for president, especially one so closely aligned to bush's policies.
But then, I couldn't understand how so many people could vote against their own self interest in 2004 either.
I know that the American public is not very bright, but it always amazes me when people purposely hurt themselves. Are that many people sadists?
I really can't comprehend it...
