France has a slightly less shitty electoral system than e.g. UK, US, Canada, so a party with 30% was never going to win absolute power.
They were projected with 240-310 seats (out of 577) before the Centrists and Left agreed to cooperate. If things were a little more dysfunctional, it could very well have ended up very ugly.
To be perfectly honest, I’d rather have President Biden than President Harris, but I’ll take any non-fascist over fascism.
