I still fail to see what people like about Macron. My guess is that it's a lot of French people from the left and center who want a new wave, and that are seduced by Macron showing a lo of "non-french" things : if I remember correctly his first big political moment was in London, and choosing to speak in English in a meeting in Berlin (when translation was offered to him). It's quite significant because, and this is something many non-French people may not know, just as much as there is some form of (sometimes misplaced) "French pride", just as much is there a french intellectual form of snobism to appear "better than French". Not to be mistaken with a true form of diversity/universalism/whatever, it's a form of "openess" to a certain outside world that really is a statement to other french people : I'm above you. It's very peculiar and I realize hard to explain, and it appeals to that category of french people who see themselves that way. Renzi also somewhat had it Italy. His stance of being "anti-system" also pleases (even though he worked at Goldmann Sachs), but he looks like the first of the class so that appeals to the "bobo" (more-less hipsters) who say they want change but not too much change. Basically, he's revolution-lite, young and "anti-system" enough to appeal to some people on the Left, economically liberal and banking-world enough to appeal some on the RIght.
Really not sure he can make big waves outside of the big cities and outside a very specific category of person. I could be very wrong though.
Fillon took a serious hit. There was yet another affair that came out today, and even though he will not be under investigation it damages his position, since like all the other "holier-than-thou" people from the right he was all about "exemplarity", "cuuting costs" and "getting rid of leechers" lol. People from the traditionnal right will obviously still vote for him because they don't care as long as they can vote against the PS, but he might lose the undecided.
Really glad Hamon pulled it off today. He actually has a program with some ideas, as opposed to "programs" that were basically about managing and against or in reaction to something (as opposed to being for something). It means, I think, that's there's a real chance that a lot of people fed up with the PS could vote for Hamon, because he distanced him quite early from Hollande and Vallst. Ironically he's the most "anti-system" out of the BIg 3 (Le Pen, Fillon, Hamon,) candidates, which might win some votes from the undecided vote. There's a reason the FN was hoping for Valls to win the primary, they knew (and were right) he stood no chance against either Fillon or Le Pen, since he's a "socialist" copy of both.
Things finally got interesting with Hamon winning the primary imo.
