I'm working just north of Lyon this week (25 degrees, azure blue skies, in case you were wondering

) so I've had the opportunity to talk to a few locals about the Macron situation, and it has been most enlightening.
I think his success will ultimately be down to his ability to broker deals, with no traditional party backing its the only way he will get anything done. He seems to be going about it the right way and it seems to have certain sections of the population very energised, but on the other hand, France is extremely conservative (small c) when it comes to its political machinations. Too early to call IMO.
Le Pen really exposed her ignorance in the debates running up to the 2nd round of voting so, in that respect, I think Macron is a good choice as, regardless of her political leanings, Le Pen seemed ill-equipped to actually do the job.
As to the closer integration in Europe, arguably I think it has to be done if the European project is to survive. A lot of its current issues are down to the half-way house it currently occupies regarding the €. It is fundamentally disingenuous to say that €1 in a Greek or Spanish bank is worth the same as €1 in a German bank - which is a cornerstone of the whole European concept. I think it would have already been done
