The strangest aspect of Wednesday night’s debate was Mitt Romney’s decision to change his tax policies on the fly. Having campaigned hard on a tax proposal that called for $5 trillion in tax cuts, he said flatly that he was not offering a $5 trillion tax cut.

“I don’t have a tax cut of the scale that you’re talking about,” Romney said — even though that is exactly the tax cut he has proposed.

Was Romney for his tax plan before he was against it?
