You've made essentially three points, and there are three answers.
We looked at a single vote proportional system to try to triangulate how this might work in Canada. We don't have one here. You're lucky, as the local candidate, if you get above 40% of the vote, let alone above 50%. Once you switch the incentive of the voting system and people have an incentive to go out and vote for the candidate of their choice, knowing that their vote does still count at a regional level—the vote might not count insofar as electing somebody in their local riding, but at the regional level their vote goes to elect someone—then I think you'll see strongholds to a large extent, as we understand them in a first-past-the-post system, obliterated. We tend to impose or transpose what we're used to onto what would be a new system. Everybody's vote is counted in that way.
I forget what your third point was.
