@Setanta,
Roger, it's called representative democracy. The state legislature has the power to make this decision; they decide whether there we are represented by one Senator or by two. The only practical solution is to have them make this decision. As they are elected officials, they were chosen by us to make these decisions and are accountable to us.
As far as what Massachusetts residents want...
In case you haven't noticed, Massachusetts is a strongly Democratic state (with the occasional exception of a couple governors who had to lie about their positions to get elected). It it not difficult to predict what we want...
But anyway, State legislators have also been hearing from quite a few of us about what we want. I have certainly called mine-- and there is quite a bit of activity to get a bill that gives the Governor this power passed.
