To legitimize second choices as a valid vote at the expense of not having a better representation of people's first choice pick is wrong. And it will favour the centrist party over the left or right parties. So Cullen's idea of inoculating the Liberals against accusations of self-interest by them not having majority control over the committee, but rather all parties present in closer proportion to the votes they received from Canadians, is a fabulous idea, IMO. It would show true sincerity on the part of the Liberals, and certainly make it easier for the public to buy into the outcome of the committee.
Let's hope Trudeau listens to Cullen!
