I signed this, however I wouldn't count on Tom Corbett doing anything that doesn't benefit him or his big business interests. If you really wish to aid the fight for marijuana legalization (both medical and otherwise) in Pennsylvania you should look into John Hanger's platform and begin spreading the word. If John Hanger can win the democratic primary for governor next year then we will surely see progress made in this state. http://www.hangerforgovernor.com edit: Here's an article that NORML ran detailing John Hanger's marijuana reform platform: http://blog.norml.org/2013/08/28/pa-gubernatorial-candidate-john-hanger-marijuana-reform-can-elect-the-next-pa-governor/
