[EM] Score Sorted Margins + Sequential Monroe Voting (python code)

[Ted Stern]

Thanks for your comments, Rob!

I don't recall what I was writing about a year or two ago, but it was
probably about your approval primary idea.

If one were advocating for voting method improvements, Approval Voting
would certainly be a great place to start, and my ssmpr.py code could be
used for both single and multi-winner with a 0 to 1 range ballot.

With either Approval or Score ballots, I think one reasonable way to do a
primary would be to use SSMPR to run several different elections on the
same ballots:

Single-winner plus runner-up
Two winners (quota = 50%)
Three winners (quota = 33%)

and include all those candidates on the general election ballot.

In the worst case, this would put 7 candidates on the general ballot, but
more likely 3 to 5, since there would likely be some overlap between the
three sub-elections.  In a scenario with two larger parties having 40% and
35% strength, the 3-seat multiwinner count would ensure that any
alternative party with more than 7% strength (or appeal to factions within
the larger parties) would have a candidate on the ballot.
