Ezra Klein suggests in the latest Newsweek that President Obama needs some ?new blood? in the White House.

Fair enough. It?s too bad Klein doesn?t make the case for new ideas as well. Here?s his pitch for Obama to rehire (in a puzzling diversion from the theme of ?new blood?) Christina Romer:

She won?t bring a new perspective, but she brings the right perspective. In her final speech as chairwoman of the Council of Economic Advisers, she offered the full-throated call for more fiscal stimulus that the administration has largely abandoned. ?Concern about the deficit cannot be an excuse for leaving unemployed workers to suffer,? she said. ?We have tools that would bring unemployment down without worsening our long-run fiscal outlook, if we can only find the will and the wisdom to use them.?

Yes, what we need now is more stimulus spending. Stimulus supporters are rushing to make that case during the election season.
