So Alain Juppé invited Henri Guaino to quite the UMP, whose line on Europe he does not support (Guaino styles himself a proto-Gaullist "Europe of nations" nationalist, while Juppé is a social liberal). Copé has backed Juppé in this cat fight. What's really at stake? Two anti-Sarkozystes ganging up against a Sarko-epigone in anticipation of 2017? Perhaps. Or perhaps not.
