I don't know what the answer to your question is. I think, regardless of the voting system, the three criteria you mention play into people's decision. And they don't do it the same way for everything. I don't know if there is a voting system that favours the criteria of the party leader, the program or the local personality—or personalities.
In the case of a riding with three or four seats, local personalities obviously continue to influence voter motivation. Suppose the voting system ends up creating coalition governments. I don't think coalition governments are a calamity, a disaster. Some of the best governed countries in the world today are run by coalition governments. We can know which conditions of coalitions are good and which are bad.
The conditions are bad when voters think they are scandalous. They are good when they correspond to the choice of the voters. Coalition governments are probably the most effective way of reducing the exaggeration of the prime minister's role. If we want governments to be more collegial and less quasi-presidential, as is the tendency these days, coalition governments might be the way to do that.
