Politics is the art of the possible.
"Anybody who would certainly have voted as Scalia does would have never gotten out of committee, especially if they opposed Roe v. Wade."
Gosh you do set your sights too low!
Roberts got out of committee, and got 78 votes!
If Bush nominated Michael Luttig - known Scalia clone - we would also have been confirmed. Certainly. Not maybe. Certainly.
Not just GOP votes, but red state Democrats would not commit Hari Kari over this. they would confirm the Bush nominee.
Why? Because most Americans *want* a Judge who merely interprets the law.
