Another spin I hear lately is regarding the President's low poll numbers. They are attributing it to him trying to SAVE Terri's life. I attribute it more to people's perception that he hasn't done ENOUGH to save Terri's life.
You have nailed it. People love Bush because, despite his various flaws, he is not afraid to act on principle.
Take that away and the magic is gone. Both Bushes have been revealed as weak before a minor judge in a minor court.
