I could see Governor Tom Corbett appointing his lt. governor, Jim Cawley. He would have won a 2014 special election.
I’m not so sure he would have won considering he would be on the same ballot as Corbett when he lost by 10 points and would be inextricably tied to Corbett.
Corbett's loss was a rejection of him, not the Republicans. They even made gains in the state legislature. Given these circumstances and how 2014 was for Democrats nationally, I think Cawley or any other serious replacement would have won.
