If ranked ballots were in place in 2010 Ford would have still won. He was the first choice of nearly half the voters. We may not like it, but 2010 was probably the most representative mayoral election. The people got what they wanted.
It's true he got 47% so it's easy to say, "he'd have picked up another 3% easy" if there were ranked ballots but it's not that simple because the system itself alters how people act at the ballot box.
If I really liked Olivia Chow last year but HATED Ford and concluded I had to vote for Tory to make sure Ford didn't get in, Olivia loses my vote. There all sorts of variations on this "strategic" notion and therefore no way to know how the vote would have been different in a ranked election. I suspect Chow would have picked up more votes and she may well have had enough #2 votes to put her ahead of Doug Ford. but that's pure speculation on my part but that's also the point.
It seems logical to assume Ford had nearly half the votes anyway but maybe he gets fewer "first place" votes if people are voting in a ranked system.i suspect Pantalone would have picked up more first place votes (pure speculation, I grant) but at whose expense? It doesn't necessarily alter the outcome but either way, 47% still isn't an actual majority and a ranked system would have given him that. Ford aside, specifically, you're still giving the mayor a proper mandate and saying we want the mayor, whover s/he is. to cross that 50% threshold.
Oh, and IMHO, it's totally legit to only fill in 1 or 2 slots. The whole point is that you have a choice. If you live in a 905 municipality, you can vote for regional councillors and the top vote getters get the gig (how many varies by municipality). So, if I live in municipality where I can vote for up to 4 councillors and I only like 1 or 2 or 3, so what? You want to give people the chance to have their voice heard, not force them to fill in a list. If the ballot is 6 slots and I've only heard of the top 3, who am I helping by picking random names to fill in the bottom 3? That would be idiotic.
Most voters would have been informed enough to vote for someone like Morgan Baskin this time out but if I like Tory a lot and Chow a bit and no one else at all, that's my vote. Again, so what? It doesn't undermine the intent or function of the system at all.
