PHILADELPHIA — Gubernatorial candidates Dan Onorato and Tom Corbett visited neighborhood churches, diners and taverns Sunday on the last weekend of the campaign to win over undecided voters and make certain their supporters cast ballots on Election Day.

Both candidates concentrated on Philadelphia and its suburbs, which account for one-third of the state's 8.5 million voters.

Corbett, the state attorney general and Republican nominee, visited several black churches through early afternoon.

At the Church of the Lord Jesus Christ of the Apostolic Faith, whose complex covers a city block in south Philadelphia, he urged congregants to go to the polls.

"Go vote," he said.

"Hopefully, you'll vote for me."

Democrat Onorato began his day in his home city of Pittsburgh campaigning with Sen. Bob Casey at a diner, but within hours he was at the other end of the state being greeted by a rowdy crowd of union loyalists at a south Philadelphia tavern.

Onorato, the elected executive of Allegheny County, said he discounted speculation that turnout in heavily Democratic Philadelphia would be low on Election Day.

"I don't believe it," he shouted in the crowded bar. "I can see the excitement right now."

Independent polls have generally showed Corbett leading since the primary, although a Muhlenberg College/Allentown Morning Call tracking poll of likely voters released Sunday showed Corbett losing ground, from a 15-point lead on Wednesday to 7 points in the four-day telephone survey that ended Saturday.

"The polls are still all over the place. It's crazy," Onorato said Sunday.
