What political party system is considered fair and allows the winner to get more than 50 of the vote?

A political party system that is considered fair and allows the winner to receive more than 50% of the vote is often a majoritarian system, such as a two-round system or a ranked-choice voting system. In a two-round system, if no candidate achieves a majority in the first round, a second round is held between the top candidates, ensuring that the eventual winner has broad support. Ranked-choice voting allows voters to rank candidates, enabling a winner to emerge with a majority after multiple rounds of elimination based on voter preferences. These systems aim to reflect a more representative outcome and reduce the likelihood of a winner being elected with only a plurality of votes.
