Topeka ? A Republican leader in the Kansas House promised Friday to sponsor a bill to permit slot machines at dog and horse tracks and state-owned casinos in Dodge City and near Junction City.

Rep. John Ballou, R-Gardner, said he thought his proposal would raise $150 million a year for the state. His plan would give the state between 33 percent and 39 percent of the net revenues from the new gambling.

Ballou serves as House speaker pro tem, part of a GOP leadership team with differing views about gambling. While Ballou and Majority Leader Clay Aurand, R-Courtland, supported a gambling expansion bill last year, Speaker Doug Mays, R-Topeka, voted against the measure.

Last year’s bill set a sliding scale for the state’s share of net gambling revenues — 20 percent of the first $50 million, 22.5 percent of the next $50 million, and progressively larger percentages as profits grow. The House approved the bill, but the Senate rejected it.

Ballou said he wanted a larger share of profits for the state.

“The more money the state gets, the more likely some people say they are to vote for it,” Ballou said.

Under Ballou’s proposal, the state would get at least 33 percent, but the state Racing and Gaming Commission could set aside 3 percent each for dog and horse owners and breeders. The commission could leave those groups with nothing, increasing the state’s share of 39 percent, or some other combination.

Ballou also would reserve 1 percent of the net revenues for charity, leaving operators of the new gambling to take 60 percent. The state would own the casinos in Dodge City and near Junction City but contract with private management companies.

A task force appointed by Gov. Kathleen Sebelius last month proposed allowing a single large casino in Kansas City, Kan., slots at the tracks and video lottery terminals in fraternal lodge and veterans groups’ halls. The task force said a state board should review other casino proposals.

Sebelius appointed the task force to draft a plan for expanding gambling, but Mays said its members “didn’t exactly clarify things.”

“You still have all the interest groups that want a piece of it,” he said.
