There will be a couple of GOP squishes (e.g. - Lisa Murkowski, Susan Collins) who will get the vapors and rub their hands raw worrying about what the New York Times will say about them. But for the most part, every Republican in the Senate remembers which party is responsible for the word "Bork" being used as a verb and have not forgotten how Pat Leahy and Chuck Schumer prevented George W. Bush's Federal Court nominees from getting a hearing during the last 1 1/2 years of his presidency.
