LANCASTER

- Democrat Tom Wolf and Republican Gov. Corbett headed across Pennsylvania yesterday in their final day of campaigning in a relatively low-wattage race before voters decide who will be governor for the next four years.

Yesterday's events were to include appearances by Wolf in Lancaster and Pittsburgh, while Corbett got on a plane in Allentown to visit rallies in every media market before ending his day in his hometown of Pittsburgh.

Pollsters expect that turnout today will be below 50 percent of registered voters and lower than the two previous midterm elections. Many eyes will be on Philadelphia, Pennsylvania's liberal bastion and home to more than 1 million of the state's 8.3 million voters.

Philadelphia Democratic Party Chairman Bob Brady said that he hopes to get 350,000 to 400,000 votes for Wolf in Philadelphia to more than offset any edge Corbett would get from more conservative voters in the rest of Pennsylvania.

Wolf is trying to make Corbett the first governor in modern Pennsylvania political history to lose a re-election campaign. Corbett is seeking a second term after stumbling through his first four years. In particular, Corbett has struggled to explain budget-balancing cuts in aid to public schools in 2011 at the same time he cut business taxes.

The candidates had a busy weekend of campaigning, much of it in southeastern Pennsylvania, which, along with Philadelphia's suburbs, is home to one in three voters. The candidate who wins Philadelphia's four suburban counties - Bucks, Chester, Delaware and Montgomery - is nearly assured of a victory.

Wolf was joined in Philadelphia by President Obama on Sunday at a rally that drew thousands, while New Jersey Gov. Chris Christie made his fifth visit in as many months to help Corbett in Philadelphia's suburbs.

Both candidates are seeking any edge they can get. The Republican Party has sent fliers to households warning that Wolf has a radical agenda to take away guns - Wolf has said nothing of the sort. Meanwhile, a Wolf campaign radio ad in Philadelphia warns that Corbett favors forcing women seeking an abortion to undergo an internal ultrasound - Corbett has not said that.
