The "Condorcet Winnerwinner" is sometimes referred to as the "'''Condorcet candidate"''', "'''pairwise champion'''", or '''"beats-all winner'''",. orThe "'''Condorcet winner"''' of an [[election]] is the candidate who is preferred by more voters than any other candidate in [[Pairwise counting|pairwise matchups]]. This is determined by observing whether more voters rank or score the Condorcet winner higher than each of the other candidates than the other way around.
