How will Republicans spin their refusal to extend the middle class tax cut into being all Obama's fault?

Senate Republicans gave Senator Mitch McConnell high fives in the hallways yesterday after the Saturday Senate vote to extend the middle-class payroll tax cut 2 more months. Republican House Speaker John Boehner had promised the house would pass the bill. But Tea Party Preublicans apparently rebelled. Only tax cuts for millionaires, billionaires and the corporate jet set are “real” tax cuts that magically increase revenues—even though they never have. Tax cuts that go to the middle class, those shrink revenues and thus are wasteful deficit builders.

How will Boehner spin his last-minute reversal as having nothing to do with Republicans, and being all Obama’s fault?
