Human beings will be happier - not when they cure cancer or get to Mars or eliminate racial prejudice or flush Lake Erie but when they find ways to inhabit primitive communities again. That's my utopia.
Instead of voting for just one candidate, voters rank their preferences for candidates from first to last. If no one receives a majority of first-choice votes, the last-place candidate is eliminated and the second choices from those ballots are added to the totals for the remaining candidates. The process continues until one candidate emerges with a majority. Ireland and Australia have used the system in national elections, and it has been adopted in parts of Great Britain.
Now, the idea is starting to catch on in the USA. Louisiana residents who vote from overseas by absentee ballot already have that option. San Francisco will start using instant runoffs next year and several other municipalities, largely in the West, are preparing to go the same route.
