The Condorcet criterion states that if any one candidate could defeat all of the other candidates if they were the only two options, that candidate should be declared the winner. If all points are added up, the final score is as follows: Assuming the Borda Count Method is decisive for the choice of city, Oslo is the winner in this vote. Find out more. Each rank is assigned a number of points. The plurality system is very common in American politics. For instance, the calculation tool was first developed by Ramon Lulll in the thirteenth century. To figure out the Condorcet winner, we need to consider all pairwise elections. The majority criterion states if one choice gets the majority of the first place votes, that choice should be declared the winner. These people were able to place their rivals at the bottom of the list, thus directly eliminating many candidates.
