Montgomery County Commissioner Bruce Castor has decided he will not challenge Governor Tom Corbett in the 2014 Republican primary election.

Castor made the announcement Tuesday on his Facebook page.

"After a great deal of consideration, I have decided not to run for Governor in 2014.

I want to thank all those who encouraged and advised me over the last six months.

Simply put, my duties as Montgomery County Commissioner, a lawyer with Elliott Greenleaf, and the responsibilities to my family, make a massive undertaking such as running governor impossible for me this election cycle. I appreciate all of you who followed me here and on Twitter. Thank you. Bruce"
