I think John Roberts was a great pick, but Harriet Miers? We can thank the same base that is screaming about illegal immigration that she isn’t on the court.
Yes, you are of course correct. With the near revolt of the base, then there would be no Supreme Court justice Alito.
I think the only reason GWB pulled the Miers nomination is that he feared she could not make a proper presentation at committee hearings, not that she might have been his Souter.
