Oklahoma voters will head to the polls on Tuesday to vote in local and state elections.

Drawing the most attention is the contest for Oklahoma's only open seat in the U.S. House of Representatives. Republicans hope to take over the seat held by retiring Democratic Rep. Dan Boren. The fight for Boren’s seat is being contested by six Republicans and three Democrats.

Oklahoma holds closed primaries, and Independents cannot participate at all, though there are some non-primary races that will be decided on Tuesday.

Polls are open from 7 a.m. and close at 7 p.m. Oklahoma time.

Background: Registered Republicans and Democrats can vote in primary elections for Congress, Corporation Commission, state House, state Senate and several county-level seats such as sheriff, county commissioner, court clerk and county clerk.

Registered independent voters cannot participate in the primary, even though a number of the races will elect winners, and are not actually primaries; in several of the races, there is no opponent from another party for the candidates to face in the general election. Oklahoma has closed primaries that only allow voters to cast ballots for the party in which they are registered.

The only statewide election on the ballot is a Republican primary for a six-year term on the Oklahoma Corporation Commission.
