The GOP have their hopes pinned on a “wave” election in November, but right now several of the “statistical models” being use to predict the Senate elections are moving in the direction of Democrats. Nate Silver says the Dems have drawn almost even. The Washington Post’s prognosticators  have moved from predicting a huge Republican win to giving Dems a 51 percent edge. The New York Times now says it’s a tossup, although their model has shifted around quite a bit. Sam Wang still says 80 percent Dems.

What seems to be happening with at least some models is that as we move closer to the election the models are giving less weight to history and more to actual polls. We have many conditions in place that history says point to a Republican wave. But in real world land, it appears the wave isn’t waving.
