If Macron doesn't manage to satisfy the majority of french people during his presidency, I'm pretty sure the next elections Le Pen will get even more votes. So the pressure is on him to regain the trust of the french people in politics
You are right.
11 millions of my fellow countrymen voted for Le Pen even if she is racist and dangerous.
But I don't feel like living in a racist country. Especially in Paris, where the immigration is the most important : Macron won with 90% of votes (including mine)...
The problem is that there is no real/strong opposition against liberal politics (=Macron), except Le Pen due to its historical implantation. So, people who disagrees with liberalism don't vote at all or vote for Le Pen, just to show their disappointment.
Fortunately, this happens only during the 1st round of the elections. But it's a dangerous game. The only way to avoid Le Pen is to have a strong alternative. We have 5 years to build it...
