Is Ann going to be the next "Brock"?
Man, you are totally missing the point. David Brock went from faking being a conservative to faking being a liberal.
Ann is a conservative and she wants to see conservatism advanced. Bush is the one who is failing as conservative. His nomination of Miers is just the most recent example.
It is not that Miers might not ultimately be a reliable conservative vote, but being a Supreme Court justice is more complicated than just voting yea or nay the way Senators do. The fact that she was a good lawyer, a trial lawyer by the way, is not a qualification for a judge. It is like sending your star highschool line backer to coach the NFL team for the first time.
