A Condorcet winner is a candidate in an election who would win a head-to-head matchup against every other candidate. This concept is named after the French philosopher and mathematician Marquis de Condorcet, who studied voting systems and preferences. In a voting scenario, if a candidate consistently receives more votes than any other candidate when compared directly, they are considered the Condorcet winner. Identifying a Condorcet winner can be useful in understanding voter preferences and the overall fairness of an election. However, not all elections have a Condorcet winner, as preferences can be cyclical, leading to situations where no single candidate can win against all others. This phenomenon is known as the Condorcet paradox.
