H.L. Mencken agreed with you. Here are a few things he had to say about politicians:
“The theory behind representative government is that superior men--or at all events, men not inferior to the average in ability and integrity--are chosen to manage the public business, and that they carry on this work with reasonable intelligence and honesty. There is little support for that theory in the known facts.”
“The typical lawmaker of today is a man devoid of principle--a mere counter in a grotesque and knavish game. If the right pressure could be applied to him he would be cheerfully in favor of polygamy, astrology, or cannibalism.”
“A politician is an animal which can sit on a fence and yet keep both ears to the ground.”
“A good politician is quite as unthinkable as an honest burglar.”
“A professional politician is a professionally dishonorable man. In order to get anywhere near high office he has to make so many compromises and submit to so many humiliations that he becomes indistinguishable from a streetwalker.”
