The other parties, including the greens and the communist party, are doing better in that respect (the greens are probably close to parity, although I don't have the numbers right now).
The problem is that our greens are hopelessly divided and incoherent on a number of topics, and thus much less credible than their German counterparts. I'd never vote for them in France, whereas in Germany I'd probably vote for them (I hope that they will field Daniel Cohn-Bendit in France for the next election - now that would be something!) In the long run, we're all dead. John Maynard Keynes
The law says that parties now have to field at least 40%
