Polling places may be lonely spots Tuesday.

Secretary of State Ron Thornburgh on Friday predicted a 23 percent turnout for the primary. That would be the lowest turnout in at least 15 years, with about 380,000 Kansans casting ballots.

“Throughout the state, there are very few contested races on either party’s ballot,” Thornburgh said.

There are only 29 contested races in the 125-member House.

He also said advance voting numbers were down.

“Couple these factors with the small number of counties that have special questions on their ballot, and the result is a decrease in the number of voters going to the polls on election day,” he said.

There are 1.6 million registered voters, a 3.5 percent increase from two years ago. Of those, 46 percent are registered Republican, 27 percent are unaffiliated and 26 percent are Democrats.

Thornburgh predicted 38 percent of Republicans would vote and 18 percent of Democrats.
