I guess I'll start with strategic voting first.
Strategic voting, I would say, is far less prevalent than people might expect. I think the estimate I've heard from the past election is about 10%, but typically it's more like 3%. It's not as high as one might expect.
When we think about electoral systems, what we have to remember is that any change we would make, if we're trying to estimate what's going to happen, is based upon preferences as we know them today. But people's preferences change with the candidates and the parties on offer. If more parties are going to contest an election, we need to take that into account. It is really a big black box, such that we can't perfectly predict what is going to happen. No political scientist would really predict that Canada would have as many parties as it has.
That's, I guess, the biggest point. I can definitely start on that. Was there a specific aspect of the rest of it?
