  B       B

B wins. Now, 3 of the C voters insincerely downrank C, and
vote A, their last choice, in 1st place.

The result is that now C wins. Those voters made C win
by ranking it lower.

For the umpteenth time, I mention again that there will be polls.  If no
candidate is a clear CW, then there WILL BE strategic voting.  How many of
such candidates are acceptable to a majority (51) of the voters ?
