Well comare the picks that Rudy would make vs. a Democrat.
Let's see:
Giuliani: Kennedy and O'Connor
Clinton/Kerry/Biden/whoever: Breyer and Ginsburg
Is there a 'none of the above' option here?
I would just compare him to other pubbies...as far as dems are concerned, on gun control and abortion there would be no difference, so I'm not sure his picks would differ from theirs.
