RSP will run in 296 seats (new Leftist party)
FPM will run in 296 seats (MORENA splinter)
PES will run in 299 seats (Christian social conservative, ex-ally of MORENA.) PES failed to win 3% in 2018 and got deregistered. PES is trying to get around 3% this time around to become a registered party and get government funding.
Just some minor corrections here. FxM (Force for Mexico) is not really a Morena splinter - it is perhaps an aspiring Morena satellite - but rather the property of Pedro Haces Barba (briefly Morena senator in 2018-9) and leader of the CATEM trade union confederation, which is styling itself as the 'new generation' of Mexican trade unionism accompanying the fourth transformation (in reality he has a dark priista past and is just as nasty and crooked as old charros). There are strong signals that Ricardo Monreal, Morena's leader in the Senate, is quietly supporting the party (his daughter is a pluri candidate for FxM). It is pretending to be a centrist progressive party, playing with feminist rhetoric and claiming to be the party of youth.
RSP (Progressive Social Networks) is pretending to be a centre-left party using a bunch of cool catchphrases. In reality it is owned by Elba Esther Gordillo, La Maestra, the infamously corrupt former leaders of the teachers' union SNTE. The party's leader is her son-in-law, her grandson is in the leadership, her daughter and nephew are among the party's candidates. Gordillo's main long-term goal is to retake control of the SNTE and is allied with AMLO, so RSP would be another Morena satellite party were it to survive. In its desperate bid to pass the 3% live-or-die threshold, it is running a wonderfully random bunch of memes, clowns, dumb celebrities, foul-mouthed actors, OnlyFans models, masked luchadores and cowboy cosplayers. My favourites are Alfredo Adame (an old Televisa soap actor) who is campaigning by telling voters to f!ck their mothers, or OnlyFans model Rocío Pina who is promising free new tits for women while posing semi-nude.
PES 2.0 is indeed the same old crap as PES 1.0, and not really 'former' allies of Morena - they still very much are Morena allies, with their added value being crude homophobia and anti-abortion histrionics. Their concerns for women's wellbeing is kind of belied by the fact that Hank is among their candidates.
So all three parties goal is to prove their "worth" by passing the 3% threshold and try to join MORENA lead alliance in 2024?
