I'm quite honoured that the P.E.I. government decided to include DMP in the plebiscite in P.E.I.; however, I do disagree with using a plebiscite or a referendum to decide this issue, especially at the national level.
The first problem you get into with a referendum in Canada that you don't get into at provincial levels is what constitutes a win. If everyone votes yes except Quebec, or if everyone votes yes except Alberta, do you change the system or do you not change the system? Are we opening up the same constitutional wars we opened up in 1982?
