I'm not going to bother following the link at this point, but would like to point out that "left" and "right" in your descriptions are not too applicable at this point.  The typical expectation of "left" being allied to things like socialism and labor is certainly not the case here.  LePen is economically quite far left, and is only termed "right wing" because she refuses to buy into open borders.  I would not assume the residual socialists and greens will necessarily go for the corporatist "left".  Neither description of Macron as "center left" or LePen as "right-wing" is accurate.
