Not to get all technical on you but Clinton was not impeached, there was an impeachment process started but he was never impeached. And it was started, not because he used his position of power to coerce a young intern, but because he lied about it under oath. So if you're suggesting he "paid his dues" for his crimes (real or alleged) then I think you're a little off base. He was never impeached, and the threat of impeachment was not because he was having an affair but because he lied under oath which is illegal.
