I think that's absolutely right. We get different types of traditions. If you take, for example, Norway, the parties there have always been very democratic, very decentralized, with an organization in which it's the local party that nominates. They nominate to the regional party, they then select. and they go up towards the national party. It's a grassroots democratic process that creates each district's list, and so on. In some other countries, particularly in some developing democracies, it's much more top-down. The party elite, the leader, the headquarters, and some other groups will personally nominate the individuals who will support them. For me, that's really a problem, because then you don't get internal party democracy, which you're trying to have, as well as having external democracy in the country as a whole.
In addition to the recruitment process, which is often somewhat closed and a private matter for the parties, you can also think about open and closed lists. So, again, with the closed lists and the party position, all that the voter does is vote for the party, and then they get the complete list, and it's not able to move candidates up or candidates down that list. With an open list, voters can express a preference for a particular candidate within a complete list as well, so it gives them a bit more choice at the ballot box.
All of these are details that we need to get right if we're going to reform the electoral system, even for a mixed member system or for a pure PR system.
