Republican gubernatorial candidate Mike Pence says the key to making college more affordable is having more students graduate in four years.
He says the state should offer money to students who promise to graduate on time.
Democratic candidate John Gregg said earlier Thursday the state should set a new goal of increasing exports by 50 percent and create a regional Midwest trade alliance.
The two opponents have already rolled out many of their ideas for how they would run the state if elected governor.
Pence has called for cutting the state's income tax by 10 percent, establishing a moratorium on new regulations and improving vocational education. Gregg says he would eliminate the sales tax on gasoline, send more state contracts to Indiana businesses and promote equal pay for women.
