Well, the Fifth Republic was then in an era of reforms, all managed by De Gaulle: the French Algeria cause was totally dead, due to the referendum held earlier that year, so there is a massive crackdown on the OAS. Still, as the referendum on the election of the President by universal suffrage: in the special election by the 800 great electors, the headless Gaullists wouldn't manage to chose a reliable candidate (Prime Minister Pompidou had just arrived in power, and Debré had just been dismissed and wasn't popular: he was to be terribly beaten in fall 1962), and most of the French prominent people don't feel left-wing at all, so no victory for Mendès; as of the Radical head of the Senatorial opposition to De Gaulle, Gaston Monnerville, there is no option for a coloured President of the Republic. So a classical right-wing politician is elected, such as former Prime Minister and current Minister of Finance Antoine Pinay or former Prime Minister Pierre Pfilmin. As they are members of the classical right (Pinay had begun his career under Vichy), the reforms are stopped, and the Fifth Republic becomes a replica of the Fourth Republic, even if it gives more powers to the Presidency, less all the troubles that have been settled by De Gaulle, from the economic crisis (and Pinay was the one who settled them) to the decolonization wars. Maybe French politics become, without the terrible personnality of De Gaulle, less right-wing oriented.
