The purpose of DVC is to promote electoral reform in Canada, not promote one system over another.
The two primary options are (in no particular order): Preferential Voting (ranked ballot) and Proportional Representation (particularly Mixed-Member Proportional and Single Transferable Vote variations.)
I believe the best course of action is to hold a rational, federal debate on the issue and then let Canadians decide.
Unfortunately, the debate has become mired in the same hyper-partisan, polarizing politics that corrupt Parliament — ironically, the same kind of politics First-Past-the-Post engenders. Instead of discussing the issue like adults, many electoral reformers are waging war against the opposing system.
Instead of engaging Canadians in the debate — building the widespread, grassroots support required for action — this behavior is turning people off of voting reform.
The real issue is getting rid of corrupt First-Past-the-Post. Either PR or PV will bring democracy to Canada. Voting reformers should persuade Canadians on the merits of their system, not manipulate them.
