[EM] Student government - what voting system to recommend?

Yes, Condorcet would probably work in - say - a U.S. presidential election.
Enough legitimate
non-"Pro Wrestler" types would run to keep those candidates from winning.
Anyway,
pro wrestlers do win fluke elections even in plurality - witness Jesse
Ventura in Minnesota a few years back.
There is still the "later-no-harm" issue, though, and I think that many
voters would bullet vote - especially the major party supporters (which are
the ones who may in fact benefit immensely from bullet voting).

However, in a situation like my student government, there would be less
interest in running -  and the possibility of a "Monster Raving Loony" type
candidate winning would be far higher...

On MMP - I wonder if anyone has looked into the semi-proportional
nonpartisan MMP I mentioned earlier...  It would do a best-loser top-up by %
of vote without taking into consideration parties.  It almost seems like it
would be pretty close to PR, except for parties who can't even manage a
reasonable number of 2nd or 3rd place showings in a constituency and for
major parties who win a strong majority government.  It does seem like it
would help the Liberal Democrat (UK)/NDP (Canada) type parties, and even
smaller parties would gain a seat hear and there...
