The '''Borda count''' is a [[voting system]] devised by [[Jean-Charles de Borda]] (who was apparently preceded by [[Nicholas of Cusa]] [http://www-gap.dcs.st-and.ac.uk/~history/HistTopics/Voting.html]), used for single or multiple-seat [[election]]s. It is used for parliamentary elections in Nauru and Slovenia. This form of voting is also extremely popular in determining awards for sports in the United States. It is used in determining the Most Valuable Player in Major League Baseball, the national championship of college football, the Eurovision Song Contest, as well as many others.

points, down to an ''n''th rank being worth 1 point. A candidate's score is the sum of the number of points they received. The highest-scoring candidate is elected.
 
In the trivial case of ''n''=1, this is mathematically identical to [[plurality voting]].
 
In the trivial (limiting case) of n=∞, allowing truncated preferences, this is mathematically identical to [[approval voting]]. This is approximately true for large ''n'' the votes offered to ranked candidates will be approximately equal and nonranked candidates will all get zero votes. Example, if ''n''=10, and I rank only only three choices, they each get 10,9,8 votes respectively, normalized to 1.0, 0.9, 0.8 votes, close to 1.0 vote for an equivalent vote offered in Approval.
Line 51 ⟶ 49:
 
In addition to tactical voting, [[strategic nomination]] considerations reign supreme in the Borda count. Running multiple, similar candidates may enhance a party's chance of winning the election by increasing the point differences with opposing candidates, if the party is allowed to advance more than one candidate for consideration.
