Calculate the Condorcet winner. The point values for all ballots are totaled, and the candidate with the largest point total is the winner. Borda Count Method. If there are four options, the top rank is therefore awarded with 4 points. In the original variant, the lowest-ranked candidate gets 0 points, the next-lowest gets 1 point, etc., and the highest-ranked candidate gets n 1 points, where n is the number of candidates. If a list of candidates to ignore is given, those candidates will be treated as if they dropped out of the election between the collection and counting of the ballots. Other broadly acceptable options and common voting systems are the plurality and majority systems. It originates from an election process in which candidates are ranked by voters in preferential order. The votes for where to hold the conference were: Use the Borda count method to determine the winning town for the conference. For example, the lowest rank gets 1 point, and each consecutive spot on the list gets an extra point.
