She'll get Arlen Specter's vote for sure.
Specter won't be alone - the Senate GOP has proven itself to be completely spineless on Dem SCOTUS appointments in the past. Didn't Orrin Hatch co-sponsor Ruth Ginsburg's nomination? Despite all the unprecedented (or now, newly-precedented) judicial nominee fillibusters by the Senate Dems the last for years, I think the Senate GOP will revert to form should John Kerry win on Tuesday.
The only think I can say is that the day HRC wins confirmation in a Senate that has at least 41 GOP Senators is the day I stop voting Republican forever.
