Whether you thought Romney won or Obama lost, I think we can all agree that Romney was far more enthusiastic during last night’s debate. I wonder if Jonathan Chait has it right when he analyzes that this way:

Romney won the debate in no small part because he adopted a policy of simply lying about his policies. Probably the best way to understand Obama’s listless performance is that he was prepared to debate the claims Romney has been making for the entire campaign, and Romney switched up and started making different and utterly bogus ones. Obama, perhaps, was not prepared for that, and he certainly didn’t think quickly enough on his feet to adjust to it.

Perhaps the biggest lie was his claim that he didn’t have a $5 trillion tax cut. Of course he does.

A Tax Policy Center analysis of Romney’s proposal for a 20 percent across-the-board tax cut in all federal income tax rates, eliminating the Alternative Minimum Tax, eliminating the estate tax and other tax reductions, would reduce federal revenue $480 billion in 2015. This amounts to $5 trillion over the decade.

He’s denied it because he claims the Tax Policy Center is partisan and wrong, but no neutral party thinks that.

In fact, the people at Think Progress found that Romney put forth 27 myths in the 38 minutes he spoke during the debate last night. Another one is the now-famous $716 billion that the ACA takes away from health care insurers in the Medicare plan, not beneficiaries. Funny, Romney’s running mate Paul Ryan’s budget took the same amount away from Medicare, but his plan took it from users, not providers.

Another myth: that Romney’s plan for health care insurance would cover people with pre-existing conditions. Nope. Only if they had continuous coverage (through COBRA, I suppose) would they be covered. If they lost coverage, too bad and good luck getting new health insurance.
