Preliminary results of exit polls have found that about half of the voters in Ohio are giving President Barack Obama a failing grade for his job performance.
Also, about half of Ohioans say they think Obama's federal health care law went too far while just 2 in 5 thought it didn't do enough.
But about half say Ohio Republican Gov. John Kasich has done a good job of handling implementation of the law. The governor has been criticized by some conservatives over his decision to expand Medicaid under the new law. He faced Democrat Ed FitzGerald.
