PROVIDED ALL the elections fit this description, that would make Plurality 
more tolerable.  A suitable voting method will:
      Avoid causing any complications of voting when such as the above two 
major candidates occur - which may be a majority of all races.
      Allow voters to express their desires with minimum pain for races 
that they see as more complicated.

Multiple candidates from the same party does not deserve special emphasis 
here:
      Plurality needs primaries because such combinations of candidates 
cause it trouble in the general election.
      But multiple parties can nominate similar candidates, hurting Plurality.
      Condorcet and Approval care little because voters can vote for 
multiple candidates.
