But the only real puzzle here is the persistence of the pundit delusion, the belief that the stuff of daily political reporting — who won the news cycle, who had the snappiest comeback — actually matters.

This delusion is, of course, most prevalent among pundits themselves, but it’s also widespread among political operatives. And I’d argue that susceptibility to the pundit delusion is part of the Obama administration’s problem…

The best way for Mr. Obama to have avoided an electoral setback this fall would have been enacting a stimulus that matched the scale of the economic crisis. Obviously, he didn’t do that. Maybe he couldn’t have passed an adequate-sized plan, but the fact is that he didn’t even try. True, senior economic officials reportedly downplayed the need for a really big effort, in effect overruling their staff; but it’s also clear that political advisers believed that a smaller package would get more friendly headlines, and that the administration would look better if it won its first big Congressional test.
