This site wants you to vote strategically to avoid splitting the anti-conservative vote on the assumption that all things being equal, the conservatives are much worse for the environment than any of the other parties. This is not really how you want an election to be decided, but a party that represents the minority of Canadians should not get a parliamentary majority simply because of a flawed voting system.
I would heartily endorse a preferential ballot system for us. How does this work?
Instant-runoff voting (IRV) is a voting system used for single-winner elections in which voters have one vote and rank candidates in order of preference. If no candidate receives a majority of first preference rankings, the candidate with the fewest number of votes is eliminated and that candidate’s votes redistributed to the voters’ next preferences among the remaining candidates. This process is repeated until one candidate has a majority of votes among candidates not eliminated. The term “instant runoff” is used because IRV is said to simulate a series of run-off elections tallied in rounds, as in an exhaustive ballot election.
Under this system, if you like the Green Party the best because of their environmental policies, but know they cannot win, you can still vote for them. Just have the liberals/NDP as the second choice. It is overwhelmingly likely that if you like the Green Party policies, you like the policies of the conservatives more than the policies of the liberals or the NDP. With our current system, that’s exactly what your vote will say. Your vote for a Green Party candidate in this election is essentially a vote for the Conservatives.
In the absence of the preferential ballot, or instant runoff voting, using web 2.0 methods to vote strategically is the next best thing, and a great idea!
