I think Republicans are going to get the House back… But frankly, I think we’re being very conservative with that [Republicans need to win 39 Democratic seats to get control of the House, and Mr. Cook’s current estimate is that they are in line for a 35- to 45-seat gain]. The odds of it being higher than that range are a lot better than lower.
