[EM] fully proportional representation with single member districts

[Ross Hyman]

Here is an electoral reform proposal for a county like Israel, which currently uses a closed list proportional system for the entire country and where there have been complaints that the people on a party list are not chosen democratically and are not geographically representative. 
The proposal retains full proportional representation and does so with single winner districts.  The basic idea is to hold the “primary” election after the “general election."
Each voter registers with a party.  The number of voters who are registered for each party on the “general election” date is used to determine the number of seats for each party using the country's standard method, such as  D’Hont.  No actual election needs to be held on that day.
Next the “primary election” is held.   There is a separate primary for each party but they are all held in the same day.  Say party A has earned N seats in the general election.  For party A's primary, the country is divided up into N districts with the same number of Party A members in each district (This could be done through an automated scheme).  The same is done for each party.  The districts from different parties will likely overlap with each other. 
Voters who were registered for Party A on general election day get to vote in the Party A primary in the party A district where they reside. An appropriate single winner election method can be used.   For a party that gets one seat, the entire country is one district.  For a party that gets two seats, the country will be divided into two.  But the dividing line can be different for a different party with two seats, since the distribution of party members will likely be different for both parties. Etc.
In this system party membership needs to be public so that candidates know whose votes they are  campaigning for.
