Clinton was impeached but not convicted.
Huge difference.
And since Baraq is black (well sort of) there’s ZERO chance he would be impeached by a Republican congress.
Perhaps Obama would be impeached; perhaps, as you say, Republicans would be too cowardly to proceed. Regardless, an Obama re-elected by a plurality (very likely the most that he could get) would be defensive and weak because it woud become obvious that his support was illusion.
But you are so afraid of a skinny fraud that you're willing to invest all aspects of Republican leadership and power in a politician with a rock-solid RECORD of advancing every single major liberal statist cause that you have, presumably, been voting Republican all these years to oppose. All because you're frightened.
Conservatives like you make me think of a line in "A Few Good Men."
You're such a coward. I can't believe they let you wear a uniform.
