Yes, and it's not completely hypothetical. In New Brunswick when Frank McKenna won with 60% of the vote, Mr. Hatfield got 40% and no seats in the legislature.
On the other hand, at the federal level and with the regionalization of our system, a party's not going to win 40% of the vote and get zero seats.
I would also caution that it's very dangerous to take past election results and extrapolate them to expose them to some other system because the cast of players would be different, and everybody responds to incentives: voters, parties, interest groups. I think that's a bit of a dangerous game to play, but yes of course, when you get those incredibly lopsided results that don't reflect the popular vote, that is a shortcoming of our system. That was very important in the New Brunswick case that Ms. May mentioned, but also in Prince Edward Island where they had a series of elections in the nineties that returned one or two opposition members.
