One of the most important is that it optimizes voter participation
instead of relegating either the first round to a low-turnout primary or the second round to a low-turnout standard runoff.
by consolidating the runoff with the primary, IRV saves a great deal of money both in government election administration and in the
cost to candidates of running two campaigns.
Thirdly, IRV encourages candidates to run coopererative campaigns where each
seeks secondary support from voters whose first preference is another candidate, thus diminishing campaign mudslinging.
Instant Runoff Voting is in use in San Francisco, Oakland, Berkeley, San Leandro, California and has been provisionally
approved in Santa Clara County.
It has also been adopted by Portland, Maine, and both Milwaukee and Saint Paul, Minnesota.
Academy of Motion Picture Arts and Sciences uses IRV in its selection of the Oscar for best picture.
(also known as the Alternative Vote, Preference or Preferential Voting, and Ranked Choice Ballots) has been used since 1921 to elect
the President of Ireland, and to elect the lower House of the Australian Federal Parliament since 1919 (where it is also used to elect
the lower house for most states of Australia).
