TOPEKA, Kan. (AP) — The Latest on the Kansas primary (all times local):

6:25 p.m.

The top election official in Kansas’ most populous county says turnout in the primary election should be close to what he had expected.

Johnson County Election Commissioner Ronnie Metsker said Tuesday evening that he believes 77,000 or 78,000 voters in the county will cast ballots. The county has about 389,000 registered voters, so that would be a turnout of about 20 percent.

Kansas Secretary of State Kris Kobach has predicted that 24 percent of the state’s registered voters will cast ballots. He also said he believed turnout in Johnson County would be slightly lower than the statewide figure.

State elections director Bryan Caskey said the secretary of state’s office hasn’t seen anything to think its prediction is off.
