[EM] Asset-MMP

[Kristofer Munsterhjelm]

A thought/sketch for an MMP method that doesn't need to formalize parties:

First elect candidates as usual, possibly with small districts.

Then elect an asset council of say 10x the number of candidates as were 
elected, based on the surpluses from the first elections (i.e. those who 
didn't get their candidate elected), using a weighted vote method like 
EPR or Chamberlin-Courant.

The asset council members then negotiate based on their voting power to 
elect a certain number of top-up seats, after which the asset council 
dissolves.

The surplus calculation should be set up so that if everybody votes 
party line, and the surplus representatives for any given party in the 
proportional council pool their power to get their share of party 
representatives elected, then the combined outcome is proportional by 
party as with ordinary MMP.

The hard part is doing the "surplus distribution" because in a good 
single-winner method, the voters who don't get their candidate elected 
still contribute to pulling the winner in their direction. I think 
Schulze did something Monroe-based in his STV-MMP method; perhaps that 
could be repurposed.
