Following the European elections Macron decided in all his hubris and contempt, to dissolve the Assembly. The far right basically won the elections, (roughly 40% of the votes with a 60% abstention rate, definitely not legitimate but they still won).

The dissolution called for early parliamentary elections, which was pretty much unexpected. The far right rejoiced, especially because of their fresh results from the European elections. Pretty much all the left parties panicked (justifiably so) and banded together as the NFP.

France being a shit country when it comes to actual press freedom (90% of mass media are controlled by a dozen people roughly, mostly billionaires, including Vincent Bolloré, our very own Rupert Murdoch), the media unleashed an absolute massive amount of right wing and far right propaganda to discredit the NFP and its program (supported by multiple economists, including but not limited to, Esther Duflo the Economy Nobel price laureate, specialized in poverty).

Said program is fairly softly leftist, with a big emphasis on massively raising tax revenue for the richest people and increasing public spending for everyone else. It got demonized by the bourgeois owned media and our own brainwashed population.

The first round of the election projected an absolute majority of RN in the assembly. With a significant number of three people in the second round, the NFP removed all its candidates that ended up third, the current ruling party took its time but ended up doing the same to limit vote division and prevent a far right massacre.

With a massive mobilization, the leftist party ended up with a majority apparently, which is good, but not really good enough to wreck shit up like they wanted. Now we can take a breather and hope they won't go back to their petty infighting and do what they promised to do, because if they don't, we will have a far right president in 2027.

It's a bit simplified obviously, but that's the gist of it.
