Socialist and nationalist like Petain, Mussolini, Marie La Peine perhaps...
That's insulting and I highly suspect trolling there. To be clear I hate nationalism, by socialism I'm referring to philosophical ideals ; I consider that humanism is an essential dimension of it.
Marine Le Pen would not like being called 'socialist', believe me. She is clearly far-right, there's no argument about it. People that vote for her know they give their vote to far-right. The accepted theory is that they usually get scared during the last round, and don't vote. That's the main line of Emmanuel Macron's strategy for 2022 : being the only alternative. Which sort of kills the democratic process.
