The Ohio Liberty Coalition today came out against Gov. John Kasich's proposed severance tax increase on gas-oil drilling.
The governor's proposal is "unnecessary and unwise," said Tom Zawistowski, president of the group that represents 75 conservative liberty-minded grass-roots groups across Ohio.
He argued that Ohio should take advantage of its tax advantage to attract more drilling for natural gas and oil and more jobs.
He also said is it is unwise to create new obstacles and tax burdens for drillers as the drilling industry tries to get started in Ohio.
The industry will boost tax revenues and Ohio shouldn't tax it unnecessarily, he said in a statement.
He called Kasich's plan to boost the severance tax to provide income tax cuts for Ohioans to be "simply redistribution of wealth."
The proposal has been tabled until after the November election by Republicans in the Ohio Legislature.
