The French are a classy lot. Truly, the takedown of François Fillon is a thing of beauty.
Might there be a deal between Benoît Hamon and Jean-Luc Mélenchon, in the former's favour?
Only if Hamon gave up his Thatcherite anti-industrialism.
And only if he agreed with Mélenchon that it is, "impossible to achieve the democratic change needed in the EU, all power belonging to technocrats with no popular legitimacy."
Whoever is the second round candidate against Marine Le Pen will be guaranteed to beat her.
Therefore, it is possible, and thus morally obligatory, to insist on the right candidate.
