The voting system for Eurovision is very interesting: the system of giving 12 points to each country’s favourite, 10 points to its second favourite, and so on, is a form of what political scientists call the Borda Count. As you no doubt know, this system delivered victory for Azerbaijan.
Azerbaijan would have won under the Alternative Vote system that was proposed in the referendum earlier this month as well. But different voting systems would have produced different results. Bosnia would have won under First Past the Post. Under the Supplementary Vote system (which is used to elect the London mayor), Italy would have won. And if each country had been able to vote for its favourite ten acts without ranking them (a form of what’s called Approval Voting), Sweden would have won.
Unfortunately, I can’t find a system that gives victory to Jedward. Still, the moral is: let no one ever tell you that the voting system doesn’t matter!
