Republican Brian Bilbray has won the much-discussed race to fill the House seat of the now-imprisoned Duke Cunningham. This will come as a blow to Democrats and mediacrats who, as usual, got themselves all excited about taking a safe GOP seat as a harbinger of Republican disaster come November. But the question is whether Republicans are going to get overexcited by the results too, and overestimate the meaning of this victory — which may simply be a very mild indicator that the public is not, in fact, in a revolutionary mood.
