Kansas Gov. Jeff Colyer conceded to Secretary of State Kris Kobach in the state’s gubernatorial Republican primary Tuesday night, just a week after the vote counts resulted in “one of the closest races in Kansas history,” The Washington Post reports. “I’ve just had a conversation with [Kobach] and I congratulated him on his success and I repeated my determination to keep this seat in Republican hands,” Colyer said. “The numbers are just not there unless we were to go to extraordinary measures.” The governor announced his concession after the vote count from Johnson County increased Trump-endorsed Kobach’s lead. Last week, Colyer demanded that Kobach step down from his position after Colyer’s campaign alleged that Kobach’s office was telling county officials not to count certain ballots. Colyer’s campaign also set up a hotline for voters to call and report “voter integrity” issues, but Colyer said on Tuesday that he does not plan on taking the matter to court or asking for a recount. Kobach will face Democratic candidate Sen. Laura Kelly and independent Greg Orman in November.
