The combined population of those 3 regions barely breaks the 1 million mark. And that's assuming a 100% tally for Le Pen, which she didn't get (it was 75%, 77%, and 65%)... so that's around 700.000 votes for Le Pen in these 3 regions.
But altogether France has 66 million people.

Surely people knew to check a simple population chart before getting hyped up for a victory after a 3 state sweep?

It's like when a candidate loses an election but the map graph of the country is mostly painted their color.... and people forget the regions with the losing candidate color actually have the least amount of people, like rural areas which in total amount to 35% of the population - only a minor portion of the size of the territory is dense urban areas, but they amount to 65% of the population so that's what matters lol, not having most of the map painted one color which is mostly low population areas.

Look at the number of votes, not the number of regions Le Pen was popular in.
