Polls close at 8 p.m. this evening, and most of Michigan is in the eastern time zone. But the four counties of Dickinson, Gogebic, Iron, and Menominee in the western Upper Peninsula are in the Central Time Zone.

The closeness of the race suggests that we probably won’t have a rerun of Florida, and have the networks calling the state at 8:01 p.m. eastern, when polls are still open for an hour in those four counties.

Turnout is projected to be about 20 percent of registered voters.
