A coalition of tea party groups says Republican Governor John Kasich's plan to raise the severance tax on oil and gas drillers to fund an income tax cut is "unnecessary and unwise." The idea remains stalled in the GOP-controlled Legislature. The Ohio Liberty Coalition is telling its members to urge lawmakers to oppose the proposal. The group's president says Kasich should trim state spending if he want cut taxes. Public opinion polls indicate voters support Kasich's proposal.
