Rafferty for AG?

We said we had The Scoop on Montco DA Risa Ferman throwing her hat in the ring for the state Attorney General's seat, and we still haven't heard a difinitive no, but, now state Sen. John Rafferty is definitely throwing is figurative hat (The Scoop has never seen John in a hat) in the ring. So, is the county DA deferring to the state senator?
