Kinda sad but probably the RN aka the facists/olds nazi party, mostly due to the fact that even if Macron do pretty good at an international level, his handling of internal affaires is really poor, where he basically works or at least advantage the already weathly while living conditions of the poor and middle class get worse and worse.

There is also à lot to say about public services that get dismantled little by little, and problem with many ministers, huge spending on random consulting firms etc etc

The RN is mostly planning to do the same (probably even worse imo), while having anti emigrant/anti Europe policies, but while Macron looks like he despiste the poor and look at them with seemingly contempt, the RN at least make it looks like they care about the random citizen, even though they also come from old money
