John McCain’s views seem to have evolved since four days ago when he told The Three Dumbest People on Television that he would “do everything in my power to block the nomination of Susan Rice to be Secretary of State.”

Now he won’t allow anyone to become Secretary of State until, well, pudding.

Sen. John McCain (R-AZ) is demanding that U.S. Ambassador to the United Nations Susan Rice go on television and apologize for her characterization of September attacks in Benghazi if she has any hope of being appointed the next secretary of state.

Today, though, McCain also told Bob Schieffer (average age = 75):

Under the present circumstances, until we find out all the information as to what happened, I don’t think you could want to support any nominee right now! Because this is very, very serious…”

Of course, not attending briefings so he can conduct press conferences to demand more information is one way to ensure he’s not getting the information he claims to now need to confirm anyone as Secretary of State. So until John McCain gets his pudding, in the form of an appearance by Susan Rice on Face the Nation to admit her vast errors in being briefed, and until John McCain is satisfied with whatever answers are provided to him about Benghazi, he’s not prepared to let any nomination to be Secretary of State to go forward.

Anyone’s nomination.

It probably gladdens the hearts of Team Obama that they can now label John McCain entirely obstructionist, and therefore ask the Senate to go around him to confirm a nominee. Going on a Sunday program to declare himself unwilling to support any nominee is about as obstructionist as a Senator can get — and removes him from the realm of seriousness.

But — pudding!

Time for McCain’s family to return to his apartment in Arlington and perhaps perform an intervention. Meghan, bring pudding. He’s become less and less understandable in his ravings, and it’s obvious no one is tending him. Goddess only knows how he must smell.
