[EM] Query for Approval advocates

[John B. Hodges]

Greetings- I am continuing to explore Chris Benham's proposed voting 
method, Generalized Bucklin. In the current version, in the 
single-seat case it strongly resembles Majority Choice Approval, 
except that there are as many possible ranks as there are candidates.

I know very little about MCA; in particular I don't know what you do 
if no candidate gets a majority. I gather that first-rank votes are 
tallied first, and if no one gets 50% approval then second-rank votes 
are added, and so forth, just as in Generalized Bucklin. The question 
I have is this: what if you STILL don't get a majority? For example, 
what if there are many, many candidates, the electorate is pretty 
close to evenly split, and everyone bullet-votes for their favorite? 
I know it's a hard case; if everyone bullet-votes, all election 
systems reduce to Plurality. But how, specifically, does MCA handle 
the mechanics of it? Has anyone written a formal description of MCA?

Thanks-
