Paul Krugman and Robin Wells credit Republican unity:
[W]hy did the right do so much better a job than Obama and company of seizing the moment? We’ve already seen part of the answer: Democrats in general, and Obama in particular, were too close to Wall Street to deal effectively with a crisis that Wall Street had created. [Thomas] Frank also makes an important point: in the recent political climate, ignorance really has been strength. You might think that the hermetic intellectual universe the right has created for itself, a kind of alternative reality walled off from any evidence that might contradict faith in the wonders of free markets and the evils of government intervention, would be a liability for the GOP. And it does indeed wreak havoc with actual policymaking. In political terms, however, it has given Republicans unity and certainty where Democrats have been weak and divided.
