Talk:Majority Defeat Disqualification Approval

Plurality failure

Douglas Woodall gives this example to show that MDDA fails Plurality:

20 ab
 5 ba
24 bc
24 ca
 9 dab
 9 dbc
 9 dca

a,b,c are preferred to d by 49,49,48 voters respectively, which are not
majorities, but a>b by 62, b>c by 67 and c>a by 66, so that a, b and c
are all disqualified.  Thus MDDA elects d.  But d has 27 votes in total,
and so is debarred by b who has 29 first-preference votes.
