What is instant-runoff voting?

Also known as the alternative vote, instant runoff voting is an election method in which voters rank candidates by order of preference. It’s not massively comm on across the globe, but some mathematicians believe it to be more democratic than other widely used systems. 

Just because we have the right to vote, doesn’t mean we live in a perfect democracy. The voting system in use at an election can be decisive in its outcome . Between a majoritarian system, like first-past-the-post, a proportional system, or a mix of the two; you could have different victors. 

Perhaps none of them are the best method. And it’s not politicians or philosophers who are saying this, but economists and mathematicians. They believe that if there’s a problem with democracy, it’s partly down to flawed electoral systems. 

So many have tried to find new ways of electing leaders with an improved political process. The theory of the alternative vote system is that voters rank candidates by preference, from favourite to least favourite. If a candidate manages to be first choice among over 50% of voters, they automatically win the election. Depending on the context, that could be unlikely, especially if there are many candidates in the race. 

In the case of no majority, the least preferred candidate is removed from consideration, buzz but the votes aren’t simply thrown away. Instead, those votes go to the second favourite candidate and a new count is established. Gradually, candidates are eliminated one by one until someone has a majority.

It’s true that vote counting can be complex in an instant runoff situation. But there are advantages too. There’s only one round of voting, in theory there are no wasted votes and there is less reason for tactical voting. The system incites candidates to make pledges which appeal to the entire population, rather than targeting certain demographics.
