Not trolling.
He is one of the most unpopular politicians in the world, and yet somehow not only is the probable next president essentially his protege with exactly the same policies, but his internal enemies (the left of PS) managed to get the stigma of being associated with his administration. Not to mention the premature destruction of his rival Valls' career.
Depends on if his "protege" can actually pull it off rather than fall into the exact same trap as Hillary, which gives it to Le Pen. This does seem likely though.
Also, he didn't stop the far far leftist candidate from going up by 8 whole points. I mean I s'pose you argue that Hamon not getting completely destroyed for the sake of keeping the party still funded which stopped Melenchon from pole-vaulting over the competition via vote-split is a feat in and of itself.
That said, you might be onto something.
