CALLING OUT SENATOR HOTHEAD…. If there’s one thing Arizona Sen. John McCain (R) doesn’t like, it’s failing to get booked on a Sunday show being called out publicly for his irresponsible behavior. The conservative Republican, dubbed “Senator Hothead” by some of his colleagues (in both parties), must have been particularly incensed yesterday.

McCain announced on Monday that, going forward, he would refuse to cooperate in the Senate’s legislative process. To punish Democrats for voting to approve legislation they support, McCain said, “There will be no cooperation for the rest of the year.”

The declaration came up during yesterday’s White House press briefing with Robert Gibbs.

Helen Thomas: McCain said he’s going to oppose everything.

Gibbs: Well, yes, I find it curious that not getting your way on one thing means you’ve decided to take your toys and go home. I don’t think — it doesn’t work well for my six-year-old; I doubt it works well in the United States Senate, because we have issues that are important for his constituents and for all of America.

Look, again, when it comes to financial reform people are going to have an opportunity to weigh in on behalf of the banks or on behalf of consumers. And I’ll let their vote on that dictate which side of that ledger they feel most comfortable on.

Chip Reed: Are you comparing McCain to a six-year-old?

Gibbs: I’m saying that I think the notion that if you don’t get what you want you’re not going to cooperate on anything else is not a whole lot different than I might hear from a six-year-old.

If the taunt fits….
