Much of the state's budget is derived from the coal and gas industry. Hence, all our other taxes are low. For the past few years we have been in a budget crisis due to the drop in energy prices. The university and public schools in particular are having a real hard time as their budgets continue to be cut.
I'm not sure whether or not if this will pass. Given the current political climate and how broke we are, I've got a bad feeling.
