Les élections législatives de 2022 marquent une recomposition profonde du paysage politique français. Si 2017 a vu le dépassement du clivage droite-gauche, notamment avec l'élection d'Emmanuel Macron, suivie par la vague de députés élus de La République en marche (LRM), 2022 est l'année de la tripartition. Trois pôles de poids équivalent structurent l'offre politique.

Their reading is that French politics has evolved from two blocks (right-wing & left-wing) to three "of equivalent weight": Left, "Center" and Extreme right.

That's one reading. You might also consider that the two left & right poles are still there and it's just the extreme right that has grown, to the detriment of the former Gaullist/Chirac/Sarkozy party, now called LR. In addition, many LR have defected to Macron's LREM, which has now become the de facto mainstream right party. Similarly, Macron has been able to lure some of the more conservative socialists (or assimilated to the PS, like the present PM, Elisabeth Borne) to grow the LREM ranks and maintain the fiction that it is a fusion of right and left (yeah, right).
