OK, if Curt Schilling isn't interested, is Roger Clemens a Republican?
I don't know for 100%, but the indications are that he leans that way. The problem for anyone, famous or not, running as a Republican in MA is perilous because there isn't any real party to support them from a financial or on-the-ground GOTV standpoint. It's one of the most moribund of any state, bar none (and the most populous state with a non-competitive GOP minority).
