Now that McCain, Graham, and DeWine seem to be on board, there are two men who stand in the way of a conservative court:
(1) The President himself, if he knowingly or unknowingly appoints an O'Connor/Kennedy clone.
(2) Arlen Specter.
I think he will do the right thing ... but I wouldn't bet my life on it.
I Specter doesn't do the right thing then fire his ass; he doesn't own that position.
