Why people support the Republicans

Over at Running Scared this morning Jazz talks about Tax reform bait and switch today and asks a question:

When you take into consideration these tax issues, the passage of the demonic bankruptcy bill which Bush is about to sign, increasing attacks on environmental protections and everything else we are seeing, why are red state voters consistently continuing to vote for people who are not acting in their own best interest? And how do they continue to defend them? All of these bloggers, pundits and commentors can't possibly be exclusively in the multimillionaire strata of society. So what would make them continue to support people and policies which are directly contrary to their own personal needs and rights? Can anyone explain this?

I have a post over there where I try to answer that question.
