I don't know the exact figures, but it looks like Romney won the state senate district of the bill's sponsor.
Bu yeah, the Massachusetts senate currently has four republicans. There's no way this will pass.
He's currently occupying the former Senate seat of Scott Brown and held his State House seat, too, so yeah, this is obviously a conservative pocket of MA.
This is almost certainly the most conservative State Senate district in the state. It's elected Democrats before, but I don't think it would elect a Democrat today without a solid reason to.
