McCain Rules

Has anyone noticed yet that McCain's unhinged rant about Susan Rice and his accompanying threat to filibuster her potential nomination to State is a huge gift to Harry Reid? I have no idea how many votes he has in his own caucus for filibuster reform. All he needs is 50. But if the weak-kneed Feinsteins of the world need a better reminder of what the GOP minority is planning to do with their cloture-proof minority this year, they just got it. Time to kill the filibuster. 4evs.
