[EM] IRV in Burlington VT

[Dave Ketchum]

IRV is of interest ONLY to those considering using that - hopefully no  
one.

Condorcet would be of interest.  If ballot format permitted assigning  
multiple ranks to any candidate, educating its voters as to this  
problem would be of interest.  Otherwise, how could Condorcet be  
expected to have more trouble than Range?
