Where Butler County voters are concerned, Tuesday’s elections leave us with only one noteworthy change in Harrisburg — but that single change is a big one, occurring at the very top of the ballot.

Democrat Tom Wolf knocked off Republican Gov. Tom Corbett, making Corbett the first governor not to win re-election since Pennsylvania governors were allowed to seek a second term.

It was hardly a surprise, however. Wolf, a York businessman, took a calculated risk during the spring Democratic primary when he advertised heavily, spending his own sizable wealth, then cruised throughout the summer with double digit leads over Corbett in the popularity polls.

Wolf’s overriding campaign message was that he’s not Tom Corbett. Throughout the campaign, Wolf kept the focus on Corbett’s failures. That’s proved to be a winning strategy, and a fairly easy strategy too, given that legislators and others in Corbett’s own party seemed to be finding fault with the governor, too.

It was hard not to find fault. Corbett’s key initiatives, like liquor privatization, public pension reform and a school property tax overhaul, never came about. Jobs and economic programs seemed ineffective.

But all that Corbett-bashing by the Wolf camp leaves the electorate desiring to know more about the man they just elected to replace him.

We do know Wolf intends to impose a 5 percent extraction tax on gas wells, an objective he made clear mostly by criticizing Corbett for refusing to tax the production of natural gas. Wolf was clever to tie the extraction tax to a need for more revenue for public education.

But Wolf, as governor, will have to tax more than the gas wells to restore the half-billion-dollar-a-year shortfall for public education he successfully pinned on Corbett. There will be more taxes than just the extraction tax. Wolf hasn’t said much yet about what those taxes will amount to, or who specifically will pay them.

With his win, Wolf also inherits one of Corbett’s most sticky and as-yet unresolved problems: public employee pensions with an estimated $47 billion in unfunded future costs. Wolf has made vague references to pension obligation bonds as a possible solution — although studies have suggested bonds would increase exponentially the state’s principal and interest payments. And the bonds have been described as risky, playing a role in the recent bankruptcy of two cities in California. Should Pennsylvania taxpayers be exposed to such a risk?

Wolf will need to be clear and persuasive in the coming weeks as he forms his cabinet and agenda priorities. Both chambers of the legislature will retain Republican majorities, and Wolf — who has never held elected office until now — is likely to find at least as much friction and resistance in the legislature as his Repbublican predecessor Corbett did.

Wolf deserves applause for his electoral victory. He merits our best wishes as he prepares to take the helm of Pennsylvania government.
