Proposed MMP ballot initiative in Colorado

[DEMOREP1]

Another alternative is just to have single member districts (SMD).

An independent would win by getting a number of votes equal to at least Total
Votes/Total Seats (TV/TS) (somewhat unlikely)

A party would get seats equal to Total Party Votes x Total Seats/ Total Votes
(TPV x TS/TV).

The top vote getters of a party in all districts would get the party's seats. 

Some districts might not elect any legislator.  Other districts might elect 2
or more legislators (which is irrelevant since the voters in all districts
would get representation).  Each party would have an incentive to have
candidates in each district (unlike the current situation with plurality
winners in SMD).
