Anti-establishment RI voters

I'm trying to figure something out here. President Bush, and RI Republicans running for statewide office, generally run very strong in South County. According to a report, South County is among the nation's leaders in marijuana "consumption." Given that smoking pot is (I think) safely associable to anti-establishment behavior and that South County votes for "anti-establishment" Republicans more regularly than for "establishment" Democrats, is it possible that we conservative Rhode Islanders should propose the legalization of marijuana statewide in hopes of toppling the current Democrat establishment in our legislature?
