If the Pithlord could abolish the Senate, he would. If that is impossible, then we should just make the best of a bad situation, and leave the status quo in place. There is no way to rework the Senate without it descending into zero-sum regional competition. Triple-E means that Quebec is outnumbere 9-1. Rep-by-pop duplicates the House. The current distribution makes BC livid.
All of which is just a mildly annoying grievance as long as the Senate is unelected and therefore without the legitimacy to exercise its constitutional powers. But you add election to the mix, and you have just what we don't need -- raw regional power struggle.
So, naturally, our Prime Minister wants to get the party started now.
