An excerpt from my latest Kaiser Health News column:

Mitt Romney’s reversals on abortion, gay marriage, gun control, campaign finance and immigration leave one with the impression that when Mitt Romney is with you, he’s with you. At least until he leaves the room….

Romney once said, “I would be happy to take credit” for ObamaCare. As he should: Romney bears as much responsibility for ObamaCare as any Democrat. Now he wants to repeal it. This absurd attempt to have it both ways is turning Romney into a laughing stock. The longer he drags it out, the more oxygen he will suck out of the effort to repeal ObamaCare.

Along the way, I explain why every distinction he tries to draw between RomneyCare and ObamaCare falls flat.
