The right was never dominating the polls. They had ~30%. It was always going to play out this way. The doom and gloom was that actual fascists had 30% of the vote.
It was only individual candidates being encouraged to drop out strategically.
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.
Edit: when I say “it was always going to play out this way” l just mean the right weren’t going to win a majority. The left still seems to have done surprisingly well in the second round.
Also, it’s still shitty that the fascists won so many seats…
