*Silver was responding to this Sean Trende piece at RealClearPolitics that makes a detailed argument against the primacy of the economy in shaping political outcomes, which is well worth reading for people interested in this debate, as is Brendan Nyhan’s counterargument. I’m not qualified to evaluate the soundness of the models being presented, but I agree with Nyhan that even crediting Trende’s model, the difference here seems to be more of degree than of kind—Politico’s framing looks a little better if you accept Trende’s argument, but it’s not exonerated, either.

Update: Nyhan also has similar thoughts about the Dickerson and Politico pieces.
