2017 French Presidential Election

[Kingpoleon]

By the way, will PS just stay aside and endorse Macron in 2022 if he seeks re-election by that moment?

If Macron is elected I don't think that PS will still be a thing by 2022.

This. There will be some recomposition between 3 poles: the left (Mélenchon/Hamon electorate) , the center (around Macron) and the far right (Fillon/Le Pen)

Melencon/Hamon is far left if Fillon is far right. Melenchon is almost as left wing as Le Pen is right wing, and Hamon is just as left wing as Fillon was right wing pre-Penelopegate.
