Yes I do. Because their program matches my political opinion. Leave the European Union, get back their national sovereignty (meaning down with the EU's Schengen agreement that allows free movement of people), take back their political sovereignty (no more laws from Brussels superceding French law) and their monetary sovereignty (France controls its own currency).
I don't support people for their good looks, I support them for their ideas and intellectual integrity. If Macron would have the Front National's program, I would support him, but he's the globalist pur sang, the establishment's hand-puppet to subversively continue Hollande's failed policies.
There's of course the existential crisis Europe is going through right now and if people don't vote for the right politicians, we'll enter a point of no return very soon.
