The Democrats are not in jeopardy of losing the House. In fact, I predict they will pick up two seats, the 9th RD with Monique Johns in Jason330’s Upset Special, and Bradley Connor in the 41st RD. That would give the Dems 27 seats again, and the Republicans will have 14 seats.
The Senate is a more close run thing. As I have said before, there are three races where it is conceivable the Republican could win. They only need two seats to gain a majority of 11-10. Currently, there are 12 Democrats and 9 Republicans. Those seats are the 1st SD, with features Harris McDowell and James Spadola; the 8th SD, with David Sokola and Meredith Chapman; and the 14th SD, with Bruce Ennis and Carl Pace. It would not surprise me if Carl Pace wins, but I feel all three seats will remain with the Dems because of the Presidential turnout. If this was a midterm year, I could see all three go Republican with a lower Democratic turnout. But all three will be saved by the turnout for Hillary Clinton and Lisa Blunt Rochester. So the Senate will remain the same.
