#** "C" advances (per this step). "B" satisfies 70% of the electorate, and "C" satisfies the other 30%. So, 100% of the voters will be satisfied with one of their choices in the general election.

In 2018, [[User:RobLa]] led discussions about "[[MATT]]" and "[[MAF]]" on the [[election-methods mailing list]].<ref name=":1">{{Cite web|url=http://lists.electorama.com/pipermail/election-methods-electorama.com/2018-July/001844.html|title=[EM] A simpler approval based way of replacing the CA jungle primary|last=Lanphier|first=Rob|date=2018-07-18|website=lists.electorama.com|url-status=live|archive-url=|archive-date=|access-date=2021-02-06}}</ref><ref name=":2">{{Cite web|url=https://medium.com/@robla/replacing-the-jungle-primary-c1e844a5333b|title=Replacing the jungle primary|last=Lanphier|first=Rob|date=2018-11-25|website=Medium|language=en|access-date=2021-02-06}}</ref> They led to the creation of the "[[Maximum approval top-two]]" and the "[[Majority approval filter]]" pages here on [[electowiki]].
* "Maximum approval top-two" or "MATT" is an approval-based primary where voters use an [[W:approval voting|approval voting]] ballot to select which candidates would be acceptable to advance to the general election. The maximum approval top-two method then selects no more than two candidates to advance to a general election.<ref>{{Cite web|date=2018-2020|title=Maximum approval top-two|url=https://electowiki.org/w/index.php?title=User:RobLa/Approval-based_primary_election_methods&action=history|access-date=2021-02-06|website=Electowiki|language=en|last=|first=|archive-url=|archive-date=|url-status=live|authorlink=[[User:RobLa]] and others|authors=[[User:RobLa]] and other editors}}</ref>
* "Majority approval filter" or "MAF" is an approval-based primary election method that advances all candidates who are approved by a majority of the electorate, as well as often selecting one or more opposition candidates.
Neither MATT nor MAF took the world by storm.
Meanwhile, the [[The Center for Election Science|Center for Election Science]] helped the folks at [[STL Approves]] get off the ground in 2019. They were able to get St. Louis to switch to approval voting in the primary.<ref>{{Cite web|last=Schlinkmann|first=Jesse Bogan, Mark|title=The next mayor of St. Louis faces big challenges — and high expectations|url=https://www.stltoday.com/news/local/govt-and-politics/the-next-mayor-of-st-louis-faces-big-challenges-and-high-expectations/article_8bd547ee-9188-5c5c-8332-757073a32dbe.html|access-date=2021-02-04|website=STLtoday.com|language=en}}</ref> This method is called the "St. Louis method" on this wiki page and is described below.
