OKLAHOMA CITY (AP) - County election boards statewide are open for the first of three days of early voting ahead of Tuesday's primary election.
Voters can begin casting ballots starting at 8 a.m. Thursday for several races, including Democratic and Republican primaries in the race for Oklahoma's open U.S. Senate seat. Only Republicans and Democrats can vote in primaries in Oklahoma.
Early voting will continue at county election boards from 8 a.m. to 6 p.m. on Friday and from 9 a.m. to 2 p.m. on Saturday.
Gov. Mary Fallin and U.S. Sen. Jim Inhofe are among Republican incumbents facing a primary challenge.
This is the first year that early voting on Monday was eliminated. The Oklahoma Election Board requested the change to help election workers better prepare for Tuesday's election.
