I don't think so, Macron will be the first President in 20 years to be re-elected for a second term, the French turn against their leaders at the drop of a hat and despite this Macron gained more voters in primaries than Le Pen did from 2017. The closing of the gap in the secondaries looks more like a lazy electorate than a positive trend for Le Pen.

I also don't see where The National Rally picks up more voters from, they're kind of maxing out their demographics right now they don't look to have improved enough from five years ago to really claim there's been a further shift right to the point that they're a threat.

In the Primaries the two main centrist/left leaning candidates, Macron and Melenchon had 49.5% of the vote, the green party had another 4.65% whereas the two far right parties had 30% between them. It's about a 10% increase for both but the centre right party went from 20% to less than 5% of the vote in five years. I think France is fine, Macron being their strongest leader on an international stage for years will hopefully resonate with the electorate because I think Europe needs him for the foreseeable future but Macron swing voters are far more likely to sway a bit further left than far right in five years in my opinion.
