[EM] E/A/R voting (yet another simple 3-slot design attempt)

[Jameson Quinn]

Here's "E/A/R voting", which stands for Endorse/Accept/Reject:

Voters “Endorse”, “Accept”, or “Reject” each candidate. The winner is the
most-endorsed candidate who isn’t “overwhelmed”. A potential winner is
“overwhelmed” if there are fewer voters who don’t reject the potential
winner, than voters who don’t reject some other candidate while also rating
them at least as high as the potential winner.




(Note: there will always be at least one candidate who is not overwhelmed,
because you always count at least as many votes for a candidate when you’re
considering them as a potential winner as when you’re seeing if they
overwhelm another candidate.)


I think one good variant would be E/A/R with runoff, where a runoff is
triggered if the winner has less than 25% endorse OR less than 50% above
reject. In that case, the winner would go into a runoff against new
candidates, where new candidates can be proposed by the existing candidates
in an asset-voting style: it takes a set of candidates with more voters who
"endorse" at least one of them than voters who endorse the winner, to put
forward a new candidate. This second election would use E/A/R if there were
more than two candidates, and the winner would stand even if they still
didn't meet the 25% or 50% thresholds.
