[EM] IRV Failures

[Eric Gorr]

In a recent conversation with an IRV supporter I asked the question:

  What cases would you accept as failure of IRV?

They answered:

  Where the general public (or a significant fraction of it) failed to
  accept the results as legitimate, or at least beyond question.  The
  2000 and 2004 Presidential elections are examples of failed elections.
  San Franciso's election was heralded as a success.

They also believe that IRV has never failed to produce a fully 
satisfactory result. Can anyone provide evidence to the contrary?
