How does Romney get around an improving economy?

First off, February is a long way from November, and the recovery, such as it is, has been devilishly unpredictable. So there's that. But even assuming that the economy continues to improve, Romney is likely to stick to the script. From NY magazine's Jonathan Chait:

Romney has been claiming that President Obama's policies have "made the economy worse." Journalism fact-checkers are pummeling him for it, pointing out that the economy is not actually doing worse than when Obama took office. That's true, but, as so often occurs, the fact-checkers are being annoyingly overliteral in their interpretation of his words. Romney isn't necessarily saying that the economy is worse, merely that Obama's policies worsened the economy - that is, that the economy would have recovered more strongly in the absence of his intervention. Now, I find that claim ridiculous, as would pretty much the entire macroeconomic forecasting field. But it's not a provably false statement.
