Well said.

Do you have any specific reason to think that? I mean, it seems very unlikely to me that Le Pen will win, since Macron will get the votes from the extreme left, left, center and most moderate right.

I'm all for the democratic, pro-trade, pro globalization, pro-tolerance and human rights candidate, which would be Macron. But overconfidence and polls led to Brexit and the fall of Clinton. Le Pen should be treated as the legitimate threat she is.

Also, the extreme left voters are unreliable as hell and can easily stab you in the back. If they are anything like the American extreme left, they might just decide not to vote, protest vote or curve to the far right to go against "continuism" and be "anti-establishment".

So are the 2 close runner ups left leaning? If so, it should be an easy win for Macron and Europe.

yea that's true, big portions of the far right and far left voters are more interested in shaking up the status quo rapidly then in any of the ideals those positions propose

Hollande was doing a great job as President. I would have voted for Hollande in favour of a great President that has served France well. Gullible people are easily manipulated by lies and misinformation spread by fake news on social media.

Fillon is center-right, Melenchon is left and Hamon (who got 6%) is center-left, Dupont-Aignan (who got nearly 5%) is right as far as I can tell.

So basically Macron will a huge majority of Melenchon voters, nearly all Hamon voters and the majority of Fillon voters.
Le Pen will get a decent slice of Fillon voters and a huge majority of Dupont-Aignan voters.

At least that is what should happen, if I put the politicians in their right camps.

I agree with what you're saying in some respects, and this "everyone hold hands and stand together" stuff sounds nice on paper, but in reality, this system of free trade, mass immigration, and globalization (essentially neoliberalism) unchecked is failing in many ways, and people are begining to pick up on this. Hell, just look at the massive failure that is the World Bank and IMF for instance.. People feel they are being "sold down the river" in the favor of the almighty force of globalization. This is why there is so much of a nationalist/populist/isolationist uprising going on in the first place.. I think at a certain point, between Brexit, Trump, Tories, La Pen, etc, you have to take a step back and wonder - well why is this stuff gaining so much traction? I'm also a firm believer in the idea that power almost inherantly corrupts, and thus abosulte power corrupts aboslutely. And so at the head of these super-global power structures, you have the potential for some very influential and potentially dangerous figureheads that can influence the lives of a growing number of people. 

This isn't to say these separate societies would be, or should be at odds with eachother however. I don't believe these movements largely advocate fighting and/or distriminating against one another, nor should they. But rather, they stress sovereignty and a celebration of their unique and disctinct cultural attributes, which they can exchange with others. I believe these ideals can coexist with cooperation and peace - but I dunno, maybe I'm naive.. I'm simply looking at the results of these elections and trying to see why the trends are leading in this direction. 

I'm not a liberal. I'm a socialist
