Why isn't Obama attacking the GOP's economic plan?

Then there’s the Ryan budget and assaults on Medicare. The fact that Romney has no actual jobs plan beyond letting the free market work its magic… It’s just endless. Complete and willful vacuity. Vacuity as a matter of principle. Almost virginal vacuity, as if intercourse with facts were somehow deflowering, leading to a lapsarian state of loss of ignorance. Nothing adds up at all. No attempt is made for things to add up. Except, of course, for those core items that Romney and the congressional Republicans will agree on: cut taxes for the rich, deregulate as much as possible, and re-wreck the economy.

It’s so bad it’s almost hard to believe. I mean this literally. Via Kevin Drum and Jon Chait, I note this nugget from Robert Draper’s New York Times Magazine piece coming up Sunday. The Democratic super PAC, Priorities USA Action, did some polling on Romney. Here’s one thing they found, and place your hand below your jaw, so you don’t hurt yourself as it hits the table: “For example, when Priorities informed a focus group that Romney supported the Ryan budget plan—and thus championed ‘ending Medicare as we know it’—while also advocating tax cuts for the wealthiest Americans, the respondents simply refused to believe any politician would do such a thing.”

There’s some word beyond “perverse” for that—a politician benefiting from the fact that his plans and commitments are so radical that voters simply can’t believe he’d pursue them.
