OKLAHOMA CITY (AP) - Candidates facing runoffs in Oklahoma's primary are working through last-day chores in efforts to get out the vote.
Voter turnout typically falls between a primary election and a runoff and candidates were hopeful those who supported them in June would return to precincts on Tuesday - along with new supporters.
Top races Tuesday are two runoffs for a congressional seat from central Oklahoma. Two-term Rep. James Lankford gave up the seat this year and won the Republican nomination in a special U.S. Senate election. Democrats will also pick a nominee to run against Lankford in the fall.
Also on the ballot is a Democratic primary for state schools superintendent. The winner faces Republican Joy Hofmeister in the fall. She defeated incumbent Janet Barresi in June.
Polls open at 7 a.m.
