[EM] STV question (was: re: Hare clustering)

[Colin Champion]

Kristofer posted some thoughts about Hare-clustered multi-member PR 
which I don't understand.

Would I be right in thinking that the aim of multi-member PR, under a 
spatial model, is to elect a set of candidates for a constituency such 
that the average distance from a voter to the nearest candidate is 
minimised? In this case, does it not follow that two candidates who are 
close to each other ("belong to the same party") will ideally never be 
elected?
