[EM] Borda and majority candidates

[Bart Ingles]

When looking at votes-as-cast, it's easy to show how Borda can elect a
unanimously despised candidate:

                     Voter rating
         <---preferred               despised--->
         ----------------------------------------
 40      A                                  C D E
 60      B                                  C D E

In other words, C, D, and E are all despised candidates.  Even though B
has a 60% majority, C wins the Borda count with 200 points compared to B
with 180.
