What happens to Beyrou and Melancthon. Do they and their supporters in the Presidential election have any involvement in the Parliamentary election?

Are the Left Radicals (MRG) still about or are they being treated as a wholy owned subsidiary of the Socialists?

As I understand French political history, the centre right have been less cohesive and has created more unstable parties than the centre left. The UMP is the latest version of an attempt to contain as many fragments of the centre-right as possible within one organisation. Will it survive, without a President to follow?
