Maine became the first state in the USA yesterday to adopt ranked-choice voting (known as Alternative Vote (AV) in the UK) for gubernatorial, congressional and legislative elections. It is also sometimes called “Instant Runoff Voting” (IRV).
Although not proportional, it ensures that the winner has the support of at least half of those who have voted and expressed enough choices. It is very good for filling single offices like Presidents, Governors, Mayors, Police Commissioners and Chairpersons.
Only two of Maine’s Governors since 1974 have received more than half the votes in FPTP elections.
There are some legal questions to be answered before it becomes law, but it is a significant step in the right direction.
