Montgomery County Commissioner Bruce Castor is considering a primary challenge to Pennsylvania Gov. Tom Corbett.
"It looks to me like Governor Corbett has not fulfilled the promise he came into office with," the Republican said in an interview with PoliticsPA. "That could change and everything could end up being terrific a year from now. But if it's not I want to be in a position where I haven't sat on my hands."
In the interview, Castor criticized Corbett for the way he's dealt with unions and the privatization of state liquor sales.
Castor and Corbett have faced off before, during the 2004 GOP primary for state attorney general. Corbett defeated Castor before going on to win the general election.
Castor is the first Republican to publicly acknowledge contemplating a challenge to Corbett, whose support in the state is lukewarm. Castor's comments come just days before the annual Pennsylvania Society weekend, during which the state's political class gathers in New York City.
Former Department of Environmental Protection secretary John Hanger is the only announced Democrat in the race so far.
