ANSWER: We don't know yet. The first state polls start closing at 7 p.m. Networks like CNN will project winners based on early and absentee vote and also exit polling. It's likely they'll project states right at 7. But the key states where the vote is much closer will take much longer. Polls close every hour until the West Coast California, Washington and Oregon at 11 p.m ET. Alaska polls close at 1 a.m. ET.
