This is analogous to a Borda count in which each preference expressed by a single voter between two candidates is equivalent to a sporting fixture; it is also analogous to Copeland's method supposing that the electorate's overall preference between two candidates takes the place of a sporting fixture. 1) Look at number of candidates and compare each of them (A vs. B, A vs. C, B vs. C) 2) Whichever letter is ranked before the other letter wins the number of voters. Borda count is sometimes described as a consensus-based voting system, since it can be used to choose a more broadly acceptable option over the one with the most first-choice support. It should be noted that this option also won the majority criterion and the Condorcet criterion. A preferential election is one where voters number or rank the candidates in the order of preference. A has 15 Borda points, B has 17, and C has 10. Consider two candidates A and B, if A is ranked higher .

Everyone brings their own reasoning to the table and ranks the order they would prefer to have the meeting. In other words, if there are two seats to be filled, then the two candidates with most points win; in a three-seat election, the three candidates with most points, and so on.

When a voter utilizes burying, voters can help a more-preferred candidate by insincerely lowering the position of a less-preferred candidate on their ballot. Consider again the election from earlier. of the Pacific Islands is the use of Borda count electoral systems in two Micronesian island atolls, the Republic of Nauru and the Republic of Kiribati. There should be 25 tallies - each city most likely had at least one person rank them in each of the positions. \hline The integer-valued ranks for evaluating the candidates were justified by Laplace, who used a probabilistic model based on the law of large numbers.[5]. Today the Borda count is used for many sports rankings, award competitions, and university committee selections. \hline & 44 & 14 & 20 & 70 & 22 & 80 & 39 \\ Again, if tournament counting of ties was used, truncating ballots would make no difference, and the winner would be either A or B.

Now suppose that a third candidate B is introduced, who is a clone of C, and that the modified Borda count is used. Since we have some incomplete preference ballots, for simplicity, give every unranked candidate 1 point, the points they would normally get for last place. In the example above, Tacoma is probably the best compromise location. Some universities use it to select faculty committee members or to select student governors . \hline 3^{\text {rd }} \text { choice } & \text { Olympia } & \text { Olympia } & \text { Olympia } & \text { Puyallup } \\ These are less susceptible to manipulation.

In Russia, for example, the two largest candidates move on to the second round. Notice also that this automatically means that the Condorcet Criterion will also be violated, as Seattle would have been preferred by 51% of voters in any head-to-head comparison. This is a different approach than plurality and instant runoff voting that focus on first-choice votes; Borda Count considers every voters entire ranking to determine the outcome.
