And Le Pen probably won't even break 35% in the runoff.
She almost certainly will.
Where should the other 14% come from ?
Even in the 2015 regionals the FN did worse in the 2nd round than the 1st (28% vs. 27%).
And if all major candidates and parties line up behind Macron, it will be very hard for her to pass 35%.
NDA voters will mostly back Le Pen. So will a big chunk of Fillon ones (and most Asselineau and Cheminade supporters to, for the mighty 1% that will bring in). Add in a number Mélenchon supporters who abstain in the second round and you easily have Le Pen hitting 40%
