Thank you.
First, the less conflictual effect potentially results, or should result, from the preferential vote given that, these days, the political parties exaggerate the differences between them. They do this all the time. We have proof: six months after an election, there are always commentators who say that the new government is acting just like its predecessor, and is itself doing what it criticized in the past.
Political discourse in our electoral system leads to the exaggeration of differences between the political parties, which isn't good for voter intelligence. I think Canadians are able to understand a lot of nuances in politics and understand that it's better to have a political discourse that's a little less simplistic. That should be an effect of preferential voting, in which we aren't just interested in voters convinced of the party, but where we know that we need to hold a discussion to get the second or third preferences of the others. That is a less conflictual aspect of the political debate.
Second, there's the regional question. The first Canadian political science article I read, when I was still French, was written by Alan Cairns in the 1960s. He explained that our voting system exaggerated the regional conflicts and gave the illusion that the Quebec of the time was fully Liberal and Alberta was fully Conservative, while that wasn't true at all.
So by allowing the representation of ideological minorities in the various provinces and regions, moderate proportional representation would also reduce the level of conflict. In terms of discourse, what strikes me in Canada is how society is much less conflictual than the political discourse. Let's take political discourse, particularly in Quebec, which pits the English, the French, the independantists and so on against each other. When we look at people's behaviour, we see that they are much more understanding and cooperative, even with people with different political views and who speak a different language, than the impression given by the political discourse. It's very unfortunate.
It would be good for us to have a political discussion that is a little more intelligent, a little more nuanced. This new voting system could help with that.
I think I've forgotten the beginning of your question.
