Kevin Drum remarks on the Romney campaign's shameless lying:

In the past, you felt that maybe campaigns were at least a little bit embarrassed about this kind of thing. They'd blame it on someone else. They'd try to produce some lame defense. They'd haul out some fake white paper to give themselves cover. They'd do something. The Romney campaign just doesn't seem to care. If it works, they use it. It's like the campaign is being run by cyborgs.

Chait uses the lies to argue that Romney would govern like Bush:

The meta-message of the Bush administration for its critics was: We don’t care what you think. What climate scientists or budget crunchers or intelligence experts said didn’t matter. The Republicans had their own people who assured them that carbon emissions weren’t necessarily warming the planet and tax cuts wouldn’t lead to deficits, and these truths would reverberate on Fox News and other friendly media. In that mental state, a Republican can confidently say or do anything, and — as long as he stays true to conservative dogma — he will be hailed as virtuous and true by the only parties whose standing matters to him.
