Obama, Dems Have Big Night in Pa.

Pennsylvania helped President Barack Obama win re-election as U.S. Sen. Bob Casey fended off a feisty challenge from Republican coal magnate Tom Smith in what turned out to be a big night for Democrats in the Keystone State.

Democrats held the lead in three state row office races as of 2:30 a.m. Wednesday with close to 98 percent of the vote in, according to unofficial results.

Kathleen Kane, a former assistant district attorney from Lackawanna County, is poised to make history by becoming the first Democrat and first woman to be elected as the state's attorney general. The Republican candidate, David Freed, is a two-term district attorney in Cumberland County.

Democrat Eugene DePasquale of York leads Republican John Maher of Allegheny in the auditor general race.

Democratic incumbent Treasurer Rob McCord of Montgomery County appears close to winning a second term by defeating Republican Diana Irey Vaughan, a county commissioner from Washington County in southwestern Pennsylvania.
