Presidential elections were held in France on 26 April 1981, with a second round on 10 May. François Mitterrand defeated incumbent president, Valery Giscard d'Estaing to become the first Socialist president of the Fifth Republic. In the first round of voting on 26 April 1981, a political spectrum of ten candidates stood for election, and the leading two candidates – Mitterrand and Giscard d'Estaing – advanced to a second round. Mitterrand and his Socialist Party received 51.76% of the vote, while Giscard and his Union for French Democracy trailed with about 48.24%, a margin of 1,065,956 votes. The Socialist Party's electoral program was called 110 Propositions for France. Mitterrand served as President of France for the full seven-year term (1981–1988) and won re-election in 1988. Electoral system If Giscard's internal political handicaps had effectively "crippled" him in the initial race, the external factors that decided the 1981 election were a deadly blow. Neatly summarized in an article by Hugh Dauncey: "It was Giscard's double misfortune that his presidency should be blighted both by unprecedented economic difficulties, and by a political system which was stubbornly unreceptive to the ouverture and centralist compromise that he required for his reforms to fully succeed". The electoral and party system (political system) in France had, indeed, undergone many critical changes during the previous years. In particular the introduction of the two-round, majority vote requirement played a large role in the election of 1981. The new electoral system divided the various right and left factions within themselves during the first round, but led to right and left polarization during the second round. That forced the right and the left to strategize for both the first and second parts of the election. In the first round, candidates must present themselves as the better candidate while being careful not to remove all credibility of his/her fellow right or left candidates, as their opponents may have to run again in the next round against the opposing right or left candidate. (It is much the same in US primary elections.) In the second round, however, total unity must be achieved. That leads to the movement of both groups toward the center, with coalitions between center groups and extremists within the right and left. Division Tactics The new electoral "rules of the game," was one of the most notable factors that decided the 1981 election. The division within the right between
