[EM] New MN court affidavits by those defending non-Monotonic voting methods & IRV/STV

[Dave Ketchum]

Topic below is monotonicity, which seems discardable as a side issue.

Of more importance is IRV's NOT CARING whether more voters indicate 
preferring A>B or B>A - can even declare A the winner when a majority of 
voters prefer B of this pair.

Example:
20 A>B
15 C>B>A
10 D>B>A

Here a majority prefer B>A, but C and D have a special attraction for some 
some minorities.
