Can't agree with this, and given your other thoughtful comments I don't think you have such a un-nuanced view of the world either.
Politicians are human. They are in a tough job. Most of them are doing their best to do what they think is right for the country and their constituents. They make mistakes; that doesn't make them evil. Even my local tea party republican - Tom McClintock - isn't evil. I think he's wrong on many of the issues; I think he isn't willing to listen; I think he's desperate for a government paid position because he can't get a job in the private sector; I think he's a carpet-bagger (ran in a safe district, not where he lives). But he isn't evil. And actually, compared to other politicians, he's a lot more broke then them, so he's not even money-grabbing.
I used to live in George Miller's district; hard-working, I liked his stands on various issues, took care of his district, respected by his colleagues. Not evil; retiring now, but his replacement, DeSaulnier, is also hard-working; I've watched his career since he started running for office while owning a restaurant, and I respect him.
Most politicians are not evil; our election system certainly drives them into desperate fundraising which can lead to corruption. But that doesn't make them evil, and we seem to be unwilling to change the system, so what does that say about us?
