Because the only credible alternatives are Fillon and Le Pen and I'd kill for the chance to not have to vote for either of them.I didnt knew Macron was popular on GAF. Dunno why though. That guy does seems a bit too much economically liberal and pro-companies/CEO to my tastes.
Hamon has no chance to be in the second round. And I doubt the people who vote Fillon would vote for Hamon lol.From what I grasp from this Election Hamon vs Le Pen has more chances of Le Pen loosing than Le Pen vs Fillion
