One reason Colin Powell cited for supporting Obama was the over-the-top-rant about who is and who is not a loyal American by Rep. Michelle Bachmann. Powell says this about 40 seconds in to the interview:
And this business of, for example, a congressman from Minnesota who's going around saying let's examine all congressmen to see who is pro-America or not pro-America. We have got to stop this kind of nonsense and pull ourselves together and remember that our great strength is in our unity and in our diversity. And so that really was driving me.
