He'll be fine. Bush will pardon him and then he goes out on the lecture circuit for big $$$$. It's too bad that he had to take the bullet for the WH but that's the risk you take working for government.
Will not happen. I've supported Pres. Bush from day one, but he is NOT going to be controversial and pardon someone after promising his "full cooperation" with the investigation. This is very, very bad news. It's been a pretty sucky month, what with the Dow falling 500, Coulter blabbing, and this.
