Unfortunately as far as politics goes, I'm of the mindset that it doesn't really matter what I think about them, because it doesn't matter. Even if you have a ton of money and influence, it simply won't matter in what pundits call the swamp. The swamp is Washington D.C., you may get there with excellent ideas and ideals, but you soon realize to get anything done you need to learn how to play in the swamp. The thing is, once you learn how to play in the swamp, your ideas and ideals are covered in mud and re-election is only 2 years away!
Mostly politicians (congressmen and senators) don't arrive with any ideals or illusions. To get elected in the first place they need a war chest and that only comes with agreeing to do certain, er, political favors for moneyed interests. The US political system is based on cash for political favors, with a cursory nod to the interests of ordinary people. The best democracy money can buy, as has been said more than once. And look at it from a politician's point of view: the public is fickle, has a short attention span, doesn't want to get involved or stay informed, and expects politicians to somehow perform miracles in return for their lousy votes. Politicians have contempt for the electorate and this is something I understand.
A typical American politician is someone like John Boehner: a poor boy from a poor background, not unduly burdened with either brains or scruples, and who will retire prosperous. People enter the political arena to get something for themselves. I'm not blaming or criticising the American political system; just pointing out how it works.
