Another argument that can be used is that it maximizes the number of people who are directly represented.
If you elect using a single seat method, then you could end up with a situation where 51% of the party are represented and the other 49% aren't. With PR, if you have 5 seats, then each councilor would represent at least 1/6 of the party. This means that at least 5/6 of the party are represented on the council by someone they actually voted for.

I think the final proposal was to use proportional rankings. This will give a generally proportional result. There might be some small variations. However, if the last few councilors are elected at the same time, then they should correct any problems with the earlier stages, so you get a President that is centerist and a proportional council. > As I've said before, it's difficult to get proportional > representation for more than the two main sub-groups That isn't true, PR methods are designed to do exactly that. If a group represents 1/6 of the electorate, then they will get roughly 1/6 of the seats. However, very small groups can't be represented due to a lack of seats. > (Although I have not yet seen a description of the Schulze > proportional method, I'm confident that it has to be much > better than your current approach of using single-mark > ballots.) Right, any PR method is better than single seat methods in terms of maximising the number of people who are directly represented ---- Election-Methods mailing list - see http://electorama.com/em for list info
