Kansas Secretary of State Kris Kobach predicts 22 percent of registered voters will cast a ballot in Tuesday's primary election. That's on par with the statewide turnout in the 2008 primary, which he says is most similar to this year's contest.
Higher turnout is expected this year in the Wichita area, where Kobach says 30 percent of registered voters might show up at the polls.
"We are expecting turnout to be higher in the 4th Congressional district where there is a particularly competitive, indeed, one might even say aggressive primary going on for the Republican nomination for that seat in congress," Kobach said.
In the 4th District, former Republican Congressman Todd Tiahrt is trying to take back his old seat from incumbent Congressman Mike Pompeo.
Kobach says nearly 40,000 Kansans have already voted in advance of Tuesday's primary.
