OKLAHOMA CITY (AP) — The race for eastern Oklahoma's U.S. House seat is drawing the most attention in this year's primary elections, as Republicans look to take a seat now held by the only Democrat in the state's congressional delegation.
Polls will be open Tuesday from 7 a.m. to 7 p.m.
Six Republicans and three Democrats are running to represent the sprawling 2nd Congressional District, where Democratic U.S. Rep. Dan Boren is stepping down after four terms.
Voter registration there favors Democrats by a more than 2-to-1 margin, but Republicans have consistently won, especially in national elections.
In state legislative races, primary winners in 13 House races and four Senate districts will win the seat since no one from the opposite party filed for the post.
If needed, runoff elections will be Aug. 28.
