538 is going deep on undecided races
Control of the House of Representatives is still up in the air, and while ABC News has projected that Republicans will win the Senate, we don't know how large their majority will be. Those things both have huge implications on how much of his agenda President-elect Trump will be able to get passed.
Accordingly, we at 538 are tracking the dozens of congressional races that are still undecided over at our new live blog. Join us there for live updates, analysis and commentary until the last major race is decided. Meanwhile, our colleagues at ABC News will continue to update this live blog with reactions from last night's results.
