In addition to the statewide races mentioned below, there will be primaries for the U.S. House, and various state/local races.

West Virginia: Polls close at 7:30 PM; the first results are anticipated at 7:50 PM. The three-way battle for the Republican U.S. Senate nomination is the biggest race. Incumbent Democratic Sen. Joe Manchin is expected to easily win renomination.

Ohio:  Polls close at 7:30; results should begin to arrive by 8:00 PM.  Five candidates are vying for the Republican U.S. Senate nomination. Incumbent Democratic Sen. Sherrod Brown has no opposition. Both parties have a competitive primary for governor; incumbent John Kasich cannot run due to term limits. There's also an interesting question about redistricting that is being voted on. The current process has left the Buckeye State as one of the most gerrymandered in the country.

Indiana:  Polls close in most of the state at 6:00 PM; the Central Time Zone areas close at 7:00 PM. As in West Virginia, three Republicans are battling for the nomination. Democratic Sen. Joe Donnelly is running uncontested.

North Carolina: Polls close at 7:30 with results expected shortly thereafter. Neither U.S. Senate seat is up in 2018.
