Charlie Cook, who was the first major political commentator to note that the Republicans would come roaring back probably taking the House of Representatives, thinks that the Senate will most likely stay in Democratic hands.
Cook gives some context to the blurred conditions in the Senate races which are collectively harder to read than the onslaught coming in the House. Here is a clip from a full report in the new National Journal:
There is no clear narrative in the Senate, just bizarre ups and downs. Republicans could easily find themselves picking up as “few” as seven or as many as 10 seats. An 8-seat pickup seems about right, but that is not written with a great deal of confidence; there are way too many races separated by very few points. In some cases it is weak GOP candidates who are causing the red team to underperform, in others it is because some of these battles are in states less hospitable to the GOP.
The strong Republican tailwind that exists in much of the country is not so strong in California and Washington, and there are higher and more durable Democratic bases in states like Illinois and Pennsylvania that keep Democrats in the hunt. It is not uncommon to hear strategists say that if the environment for House Republicans is so good (or so bad for House Democrats), then the GOP gains could get truly massive and those dynamics would likely tip the closest Senate races in the same direction.
There is probably some merit to that argument. But it also seems that the problem-children candidates for Senate Republicans have been called out more than their House GOP counterparts. The GOP candidates with more exotic backgrounds and blemishes seem to be paying a greater price for it in the Senate than in the House. We will know for sure soon enough.
