The Democrats: Ask not if it will be bad, rather ask ... how bad?

It has become fashionable to speak of a Democratic comeback, but we’re not really seeing one in our forecasting models. Certainly there are some individual races — particularly on the East and West Coasts, as well as some gubernatorial contests outside these regions — that look better for Democrats than they did a few weeks ago. But we’re showing Republicans gaining ground where they need to gain it to maintain decent chances of taking over the Senate. We also show improvement for them in the House forecast this week.

Our model now estimates that the Republicans have a 72 percent chance of taking over the House, up from 67 percent last week. Moreover, they have nearly even odds of a achieving a net gain of 50 seats; their average gain in a typical simulation run was between 47 and 48 seats. However, the playing field remains very broad and considerably larger are possible, as are considerably smaller ones.

Republican gains this week are mostly the result of factors at the local level; the national environment is roughly stable. The expert forecasters whose judgment we incorporate into the model continue to revise their characterizations of races, and in almost all cases, the changes work toward the benefit of Republicans. Cook Political, for instance, in a break from its usual convention of not classifying seats held by incumbents as worse than toss-ups, this week decided to classify 10 seats currently held by Democratic incumbents, including the seat held by Alan Grayson in Florida’s 8th Congressional District, as leaning toward the Republicans.
