HOW IT UNFOLDS
At 7:30 p.m. EDT, polls close in Ohio and North Carolina.
At 8 p.m., final polls close in Florida, Illinois and Missouri.
Expect a rush of results when polls close, because of ballots cast before Tuesday or earlier in the evening. North Carolina, for example, was a big-absentee-voting state and may have close to half the votes counted in the first hour. In Florida, 95 percent of the polls close at 7 p.m.
Illinois and Missouri are expected to be slower reporting than the rest.
