This CVD site is interesting, but Jean Charles de Borda argued that we cannot
be sure the plurality winner is the most preferred candidate, on the whole,
unless he/she receives more than N-1/N of the votes, where 'N' is the number of
candidates (see Borda's article in Iain McLean and Arnold B Urken; eds.;
_Classics of Social Choice_; Ann Arbor; University of Michigan Press; 1995). In
a 3 candidate contest, for example, that means that the plurality winner must
get a super-majority of more than 2/3 of the votes before we can be sure. The
only time a mere simple majority (more than half) is enough is when there are
only 2 candidates (according to Borda's formula).
