Primary elections are scheduled in six states on Tuesday, including Pennsylvania. There, Republican Gov. Tom Corbett is unchallenged in the GOP primary, but the general election is a different story.
Corbett is considered one of the nation's most vulnerable incumbents right now and a crowded field of Democrats is lined up, in hopes of replacing him.
In his first term, Corbett apparently failed to wow Pennsylvania voters; his poll numbers remain consistently low. That has Democrats here optimistic and one name in particular is becoming a lot more familiar.
Businessman Tom Wolf dominated the airwaves early on, spending more than $6 million of his own money. That made Wolf a target for his three rivals in the primary. State Treasurer Rob McCord accuses Wolf of turning the election into an auction.
