Bush should leave the cBS moderator on. When he gets a goofball question, he can ask, "Did Dan give you that question?"
Not a bad idea. This rathergate story is getting buried, so the white house should yank CBS's press credentials, request someone else besides CBS to moderate the debate (like Fox, or better yet, a BLOGGER), and generally play hardball regarding the rules and TV involvement until they get a direct apology and Rather's resignation. On top of that, Bush can STILL ask if Dan gave you that question...
As long as they keep this story on the front burner, they can lose all the debates & still win the election.
