Borda voting system

The Borda count is a single-winner election method in which voters rank candidates in order of preference. The Borda count determines the winner of an election by giving each candidate a certain number of points corresponding to the position in which he or she is ranked by each voter. Once all votes have been counted the candidate with the most points is the winner. Because it sometimes elects broadly acceptable candidates, rather than those preferred by the majority, the Borda count is often described as a consensus-based electoral system, rather than a majoritarian one.

>>> import borda.count
>>> who_is_superman = borda.count.Election()

>>> calisto = borda.count.Candidate('calisto')
>>> calvin = borda.count.Candidate('calvin')
>>> clark = borda.count.Candidate('clark')
>>> who_is_superman.set_candidates([calisto, calvin])
>>> who_is_superman.add_candidate(clark)

>>> valentine = borda.count.Voter(who_is_superman, 'valentine')
>>> veronica = borda.count.Voter(who_is_superman, 'veronica')

>>> valentine.votes([clark, calisto, calvin])
>>> veronica.votes([clark, calvin, calisto])

>>> who_is_superman.get_winner() is clark
