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."
The blog's model also forecasts a
chance that Democrats will control at least 50 Senate seats, and is predicting a greater than 50% chance that Democrats will lose in governors' races to Republicans in at least ten states (WY, KS, OK, IA, TN, MI, PA, WI, OH, and NM), see graphic above.
