Yankin' your Cheney

I've tried to stay away from purely political posts. So for now I'll leave the heavy commentary to everyone else out there who has a take on this recent video. I'll only say this. Of course Dick Cheney is entitled to change his mind. And maybe he did so honestly. A big question is why? What were his priorities then and what are they now? And did it ever have anything to do with a moral policy?
