Canuck, its better when you have one specific person who is responsible for representing you. It stops politicians from passing the buck to the extent they can when multiple politicians represent a group of areas.
I don't know about you, but I think democratising the Senate might actually be a bad thing. The Senate has consistently been able to provide a less partisan view of politics, and developed our more progressive policy points. The Senate has been discussing legalising marijuana for 30 years already.
