The fact that those three have gone to the other side also sheds a new light on their attitude during the campaign : Janneney was one of the Gracques that anonymously called for an alliance with Bayrou in Le Monde ; Bockel liked Sarko's security laws from 2002 to 2006 (ugh) and wanted a movement to a Blairite center ; and Kouchner openly called for discussion with Bayrou a few days before the first round, when it wasn't helpful nor even clear Royal would be getting into the first round. Those three guys clearly wanted to get power more than progressive ideas' success.
The two other "left" ministers, Hirsch and Fadela Amara, are outsiders who may have the excuse of naïvety for getting into government. Un roi sans divertissement est un homme plein de misères
As you say, the others are just shamless turncoats or hopelessly naive. The worst is Kouchner, who is explicitly guarded by Levitte and has been stripped of many of theu sual administrative powers of the minister (for instance, Hortefeux has taken over visas and asilum policies). In the long run, we're all dead. John Maynard Keynes
