Because their ethics have been totally compromized..the longer their in washington the more likely the chances are they got caught taking a bribe or banging a page in the closet or maybe with a hooker some were downtown...If the other party knows about it then that's what those shiite birds call political leverage...It's what we call blackmail..the point is, when they do things that we know isn't right, when they stand in opposition to, or in support of what what makes no sense to us, it's because they can't do otherwise...Lest we find out what they are and remove them from office...
Then you take a someone like barney frank..Every knows what a POS that subhuman is, so there is nothing you can get on him that makes any difference at all...Most of use want our leaders to have the moral high-ground..But you can always find barney with the filth in the gutter...
Sometimes I think term limits might make sense...
That would explain a lot.
