i dont know where the numbers come from.  i know philly/suburbs and pittsburgh make up the majority of the voting but once you leave that area its very rural... its called Pennsyltucky for a reason.. hahaha. 

regardless, no matter what the numbers are, Corbett has said he will veto anything dealing with MMj while its considered a schedule 1 drug.  Thankfully he's probably not going to be re-elected.
