It doesn't matter. Once he's the chairman, he does what he wants and no one can stop him.
The Paraclete can. If He wants to. His Will be done.
I don't know anything about Cornyn, other than that he's a conservative. I'm wondering if he's baiting Specter, trying to make him publicly state he's not pro-abortion (I have evil fantasies of tormenting enemies -- it's the remnents of my leftist leanings).
Specter cannot be allowed to assume the Chairmanship of Judiciary. If he gets that, he'll go after conservatives with a vengence, just to prove he can.
