After today's press conference, my first thought was "I wonder how much longer Tony Snow will want to be the face of this administration." Having to suck up to the left doesn't seem like Snow's thing.
Tony's an adult. He took the job knowing the risks. He's also a happy warrior. He's going to help the President and explain the President's position. If it goes beyond something he can stand, then he'll do what he must. But he really LIKES his job...and maybe he'll go for bigger office when the time comes.
