Greg Sargent sort of gets it when he writes, “The Democrats’ political predicament on unemployment comes down to this: Dems have no way of proving the alternate scenarios — that a smaller stimulus would have resulted in more job loss, or that a larger one would have led to more job growth.”

It’s not simply that they can’t “prove” it — it isn’t so. The Keynesian multiplier turned out to be a divider — the more we spent, the less we got. It’s not simply a marketing problem or a communications problem; it’s a policy blunder. But at least the left has realized the jig is up and Obama’s failure to deliver on his jobs bonanza is now a major liability.
