Two Fat Birds, One Well-Aimed Stone?

Is there really a causal relationship between gasoline prices and obesity? A professor at Washington University believes there is and that it can be explained by people walking more and eating at restaurants less as they feel the pinch at the pump.

I dunno, I'm doubtful of that finding, but I still liked Matthew Yglesias's wistful suggestion that, "Maybe presidential candidate and weight-loss guru Mike Huckabee would like to take this insight up as part of a comprehensive anti-obesity, anti-global warming, double-whammy." What would the campaign slogan be, I wonder? How bout: Tax the Gas, Lose the Ass.

What do you think? Do I have a future as a political consultant? ... Or what?
