Bottom line: Cook’s team still has the Senate staying Republican, as he has all along, and the House probably flipping to the Dems, but now with little chance of a big wave of 40 or more seats, more like around 30 and some chance of as low as 20 in which case the GOP stays in control.
I predict we gain 6 to 9 Senate seats and lose 4 to 10 House seats.
