From Mark Twain:
"Suppose you were an idiot, and suppose you were a member of Congress; but I repeat myself."
Obviously, it has been common thought for a long time that Congress is full of buffoons. I'm not sure what it is about Washington, D.C. that attracts such a despised group of people. I guess it's because nearly everyone recognizes Congressthings only have, and always only have had, their own interests in mind. Why they can't see it, I don't know. People of common sense can.
