LR already said they won't make a coalition with LREM. They'd be at least as likely to ally with the RN. As for LFI/PC... LREM dislike them at least as much as they do the RN.
Only strategic move I see is let the RN govern until 2027 in the hope they flaceplant hard enough with no plan or coalition to hand an easy win back in the next presidential/legislative elections, which makes twisted sense given that everyone knew they were going to win in '27. Except the risk of that plan backfiring is stratospherically high, especially if the RN lands a majority (which is not unlikely as people were pissed off voting this morning, and will be even more pissed off after a dissolution).
