MONTGOMERY County Commissioner Bruce Castor is mulling a challenge to Gov. Corbett in the 2014 Republican primary.
Castor cites three reasons for thinking Corbett is vulnerable.
* Corbett's role as state attorney general in the Penn State child- abuse scandal that sent former assistant football coach Jerry Sandusky to prison is about to get a close review by a Democrat, Attorney General-elect Kathleen Kane.
"It could get very uncomfortable for the governor in very short order," Castor said.
* Corbett's political party controls both chambers of the General Assembly, but Castor sees "a visceral lack of comfort between the governor and the Legislature."
