I will only be talking about the competitive races according to Nate Silver.
6 p.m.—INDIANA and KENTUCKY
The GOP will pick up at least one seat in these two states: the Indiana 8th, where Brad Ellsworth is retiring to run a hopeless campaign for the Senate. The Democrats will keep the Kentucky 3rd, as it is a safe seat.
A note on my methodology, any race within 4 points is a tossup. Either party can win those races depending on turnout or polling errors. The tossup districts are as follows: IN-9, IN-2, and KY-6.
My prediction: The GOP will pick up the IND-8 and IND-9. The Democrats will retain KY-3, IN-2, KY-6
Republican Net Pickup: +2.
7 p.m.–GEORGIA, FLORIDA, S. CAROLINA, VIRGINIA
The Republicans will pick up at least 7 seats this hour. The FL-2, FL-24, FL-8, GA-8, VA-2, VA-5 and SC-5.
The following Democratic seats are safe: GA-12, VA-9, VA-11.
Tossups: FL-22, GA-2
The GOP will only get those 7 pickups, and the Democrats will pick up a seat of their own from the Republicans, the FL-25 and win the toss ups.
Republican Net Pickup: +6.
Total Net GOP Pickup for the night so far: +8
7:30 p.m.–NORTH CAROLINA, OHIO, WEST VIRGINIA
Safe for Dems: NC-11, OH-13
Tossups: NC-8, NC-7, NC-2, OH-6, OH-18, WV-1
Republican Pickups: OH-16, OH-15, OH-1
I think the Dems keep all the toss ups.
Republican Pickup: +3
Total Net GOP Pickup for the night so far: +11.
