[EM] Why proportional elections - Power arguments needed (Czech green party)

[Raph Frank]

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.

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.

Right, any PR method is better than single seat methods in terms of
maximising the number of people who are directly represented
