Colin Powell. He made maybe the biggest mistake ever in American politics when he went to that UN meeting and completely destroyed his reputation and good character built up over a life time. He could have been President. (In fact, I believe there were some polls out before Iraq that showed him as the #1 contender in 2008. Powell would have won easily. Don't believe 0bama would have even gotten into the race. I remember being shocked that Colin took that assignment to sell 'Iraq has weapons of mass destruction'.
