Montgomery County Commissioner Bruce Castor is mulling a challenge to Gov. Corbett in the 2014 Republican primary election. Castor cites three reasons for thinking Corbett is vulnerable.
A Castor primary challenge would likely result in a brutal race that brings up old fights. Castor ran without his party's support in the 2004 primary for attorney general, losing the Corbett. He has a less than cordial relationship with Bob Asher, the Republican National Committee member from Montgomery County who has been an ardent Corbett supporter.
Castor says he will decide by the spring whether to get into the race, giving him time to determine if he can raise the money to be competitive. To that end, Castor went public to PoliticsPA.com on Wednesday, aiming to start the conversation in advance of this weekend's Pennsylvania Society, the annual gathering of the state's political class in New York City.
