[EM] The 'Turkey' problem and limited ranks

[Alex Small]

MCA is also more likely to elect A in this scenario.  The A>B>C faction
can safely rate A preferred and B acceptable, unless they believe a
majority of the electorate is rating both B and C as preferred.  So while
MCA is not completely immune to manipulation of polls (is anything?), it's
certainly more robust than some methods.

Also, can somebody remind me what the "Turkey Problem" is?  This thread
has been going on for a while.  I seem to recall it having something to do
with a candidate winning even though a lot of people didn't really like
him that much.
