And he's quit trying to shoot them down, too. Funny how that worked out...
He's a liberal for one.
Not only that, he is power driven and to achieve his power goals he is using ALL he has to do so... which is to demagogue his only obstacle, for he has no agenda at all that is appealing to the public, thus he is striving to gain appeal the only way he can and that is to attempt to prove Dubya' isn't doing his job.
So since Dubya' has shown time and time again that he IS doing a fabulous job, this will continue to maintain the Doctors status as a loser.
