Voting
(IRV)
-
In this election, D
is the IRV
winner, even though C
is preferred
over each other candidate by approximately a 2:1 margin:
over A by 202 to 101; over B by 202 to 101;
over D by 201 to 102; and over E by 201 to 102.
-
Almost every other voting
system ever invented, would elect C.
-
That is because most of the preferences that cause those huge 2:1 victories
are ignored by IRV. IRV only examines the "simplified" votes and
ignores the rest.
