READING, Pa. (AP) — Democrat Barack Obama is back on the campaign trail in Pennsylvania. He greeted parishioners after church Sunday morning in Lebanon, then dropped by a family-style restaurant in Robesonia, where he chatted up diners and bought pies.

Pennsylvanians head to the polls on Tuesday, and the senator from Illinois told just about every diner that he needs their vote.

From there, Obama was off to Reading for a town hall meeting. As he took the stage, his campaign rolled out a new television ad assailing rival Hillary Rodham Clinton for “eleventh-hour smears, paid for by lobbyist money.”

The ad ends by asking “Isn’t that exactly what we need to change?”

Obama said he hasn’t accepted contributions from federal lobbyists, and faulted Clinton for suggesting that he has.
