If only Obama had ...

Ezra Klein

See if this structure seems familiar to you: Over the past two years, Barack Obama has done X. Now, his poll numbers have slipped to 44 percent. His party is slated to lose a lot of seats in the 2010 midterms. Obama's decision to do X is to blame.

"X" can be a lot of things. Maybe it's the decision to attempt health-care reform. Or his socialist tendencies. Or his cool, professorial demeanor. In Matt Bai's latest article, John Podesta says it's Obama's pursuit of an ambitious legislative agenda. If he'd spent less time passing legislation, he could've spent more time developing and selling popular themes. In John Judis's latest article, it's the absence of populism in Obama's speeches and policies.

The problem with the essays is that they don't consider the counterfactual. What if Obama had done not-X? Would things really be better for him? How do we know they wouldn't be worse?

Sadly, we can't hit rewind on the cosmic VCR and persuade Obama to do the other thing in the name of science. But we have had a number of presidents who did very different things, and that gives us some basis on which to make judgments. Let's start with approval ratings. Gallup's system will let me compare only four presidents at once, so I chose the last three presidents who entered office amid a recession and didn't have a country-unifying terrorist attack in their first year. That gives us Bill Clinton, Ronald Reagan and Jimmy Carter. The dashed line is an average of all recent presidents. Click on the graph for a larger version.
