Check the ballot. There are many municipal seats to be filled across Butler County.

But check again. There are few contested races.

That, says Shari Brewer, the county’s director of elections, bodes for a low turnout Tuesday.

“We might get 20 percent,” she predicted, emphasis on “might.”

Among the offices up for election are school board, township supervisors, borough council seats, mayors, tax collectors, auditors, constables, judges of election and inspectors of election.

Turnout in off-year elections like this one, with few high-profile races, often lags.

The most recent municipal elections in 2011 and 2009 had turnouts in the county of 25 percent and 26 percent, respectively.

In this year’s May primary, just 16 percent of eligible voters made it to the polls.

Of the county’s 120,469 registered voters, 61,775 are Republicans and 42,570 are Democrats.

But there appears to be little interest among voters.

“I’m not hearing a lot of talk about the election,” Brewer acknowledged. “It’s very quiet.”

She’s hearing the same thing from peers in surrounding counties.

“There just aren’t a lot of competitive races,” Brewer said. “There’s no opposition.”

Many of the offices have no candidates at all, and write-in votes could decide the winners.

For school boards, there only are two contested races — six candidates running for four seats on the Butler School Board, and two candidates vying for a lone two-year seat in Region 1 on the Slippery Rock School Board.

In Butler Township, three candidates are seeking two seats as commissioners.

Other contested races on the ballot include:

n Township supervisors in Buffalo, Center, Clinton, Cranberry, Fairview, Jefferson, Lancaster, Muddy Creek, Oakland, Summit and Washington townships.

n Council members in Butler, Chicora, Connoquenessing, Evans City, Prospect, Saxonburg, West Liberty and West Sunbury.

n Mayors in Butler, Harrisville, Karns City and West Liberty.

In Saxonburg, a race for mayor recently turned into a nonrace after Mayor Jody Pflueger Eichenlaub said that she would move out of the borough by the spring.

While she recently announced that she was out of the mayoral race, her decision was too late to have her name taken off the ballot.

The projected light turnout is no surprise to the top GOP party official in the county.

“Usually, off-year elections don’t draw a lot of attention even though these are important offices,” said Jeff Smith, chairman of the county Republican Committee.

He predicted a generally light turnout Tuesday.

“I know my expectations are not very high,” Smith said, “but I’m hoping for 25 percent.”

He said the Butler mayoral contest could buck the trend and turn out more voters in the city than otherwise might be expected.

Countywide, there are no contested races. Republicans hold all the offices.

Seeking re-election are Lisa Lotz, clerk of courts; William Young III, coroner; and Mike Slupe, sheriff.

Ben Holland, also a Republican, is unopposed in his bid to succeed longtime Controller Jack McMillin, who is retiring at the end of the year.

The ballot’s lone statewide race, for Superior Court, pits Democrat Jack McVay, an Allegheny County Common Pleas Court judge, and Republican Vic Stabile, an attorney from Cumberland County.

Two state Supreme Court justices — Max Baer, a Democrat, and Ronald Castille, a Republican — and two Superior Court judges — Susan Peikes Gantman, a Republican, and Jack Panella, a Democrat — are up for retention votes.

Meanwhile, voters will not be required to present photo identification at the polls. A Commonwealth Court judge has postponed the enforcement of the state’s voter ID law while a legal challenge over its constitutionality plays out.

All voters will be asked, but not required, to show photo ID.

But first-time voters and those casting ballots for the first time at a new polling place will be required to show either a photo ID, such as a Pennsylvania driver’s license, or a non-photo ID with the voter’s name and address, such as a utility bill.

Brewer said poll workers will provide voters without photo identification a handout explaining the law and what forms of ID are acceptable.
