Eva Joly is proving to be a lamentable choice to represent the Greens. First she said that there could be no accord between EELV and the Socialists unless the Socialists renounced the Flamanville EPR. The PS refused, and EELV signed an accord anyway, agreeing to disagree about Flamanville. But now Joly says that the accord (with the disagreement over MOX now swept under the rug) "does not engage" her. It is strictly a "parliamentary accord," not relevant to the party's candidate in the presidential election.
Add this to Joly's previous gaffes concerning Armistice Day and honoring the military, and you get a picture of a candidate who conceives of politics as striking a series of moral postures rather than moving toward specific policy goals. Moralizing has its place in public life, but it doesn't belong in the middle of a presidential campaign. Joly has demonstrated remarkable ineptitude, and the greatest service she could do to her party would be to withdraw from the race before she further embarrasses herself by draining votes that Hollande may need in the first round and would surely get anyway in the second. There are other ways to defend her principles that don't require public incoherence and the demonstration of party disunity.
