Wait, are you saying the conservatives won last time because voters were voting strategically? I'd think that it would be because the opposite was true and the Liberal and NDP parties split the vote.
No, I am saying the effect is not known, but thus far there does not seem to be much indication that it works in practice. There are many variables in play, but the end result was a Conservative majority. If strategic voting had an impact, it was insufficient, neutral or detrimental. I am not saying it cannot work under any conditions, but I will say it is unreasonable to expect the same ploy which has proven inadequate at best to suddenly turn for the better without some significant overhauls. It's certainly not an obvious conclusion that strategic voting is the right path forward, not by a long shot.
