Obama loyalists often say: “Those Republicans are so bad. They’ve tried to block us at every turn.” Yes, the G.O.P. has tried to stymie Obama; it’s been highly destructive. But the people who keep pointing that out don’t have an answer for the simplest next question: Why have they gotten away with it?

My view: It’s because too many Americans in the center-left/center-right do not feel in their guts that Obama is leading — is offering an economic plan at the scale of the problem that has a chance for bipartisan support and that makes them want to get up out of their chairs and do battle. Our situation is different from four years ago; people want to know the president has a plan for getting out of this mess.

When the Grand Bargain talks with John Boehner fell apart, Obama retreated to his base when he should have rallied the center by laying out — in detail — the Grand Bargain the country needs. That would have forced Romney to speak in detail about his plan — the Paul Ryan plan — and reveal it for what it is: a radical plan that few Americans would embrace if they understood it.
