The leader of Le Pen's party in the parliament is not Le Pen. It's a much younger and more based guy called Jordan Bardella. So even if it's true that Le Pen would cuck, she wouldn't be the one in charge of government.

Some Italians I've heard from are saying that Meloni is being hamstrung and undermined by the Senate and the President as well as the civil service, since she only has a working majority in the lower house, but it doesn't really even seem like she's trying.

What's happening in France is that the liberal parties and the commies have all agreed to form coalitions, but the right wing parties are split. The leader of the Gaullist party (Les Republicans) was ousted for saying he would entertain a coalition with the National Rally and replaced by a leadership that is refusing to even consider it, and Zemmour has been basically sidelined in his own party for similar reasons.

So even if Bardella gets the most seats, he would need an outright majority to become Prime Minister and that's not going to happen.
