[EM] MUMA with runoffs?

My apologies for the list flakiness and Electowiki. I admittedly have only
been skimming the list every so often, and I'm considering other mediums
for discussion. Migration of the wiki software is on the table, too. I
just need to make the time to play around with all of this.
Jameson's email below prompted me to say something I've been thinking about

I agree with this wholeheartedly. I'm not yet familiar with MUMA, so I
can't speak to the dynamics it introduces. I'm also looking at this with
reasonably fresh eyes. That may mean my instinct is lacking nuance y'all
Jameson, I'm also not responding to your suggested algorithm just yet. On
first skim it looks plausible and very good at a technical level, but I
haven't entirely thought through how the complexity is a necessary product.
Here's the simple two round I would propose for U.S. presidential elections:
Round 1: Simple up/down vote on all candidates (approval ballot) All
candidates over a reasonably high threshold (e.g. 40%) advance to the next
round. If no candidate reaches 40%, then only the top two advance.
Round 2: Robust single winner system. Approval would be acceptable, the
various Condorcet-compliant versions, etc.
What voters would be answering in the primary is "is this a viable
candidate that belongs on the debate stage?" Those candidates who make it
on through the first round would be presumed eligible for debate
The effect: well, it might be messy involving cases where people aren't
stingy enough with their votes, and allow crackpots through the first
round. Over time, with enough election experience, primary voters would
learn who to approve.
