Looking at her political views, you can see she is empathetic towards the French identity and favors (from her pov) patriotic ideologies. You can read more here: https://en.m.wikipedia.org/wiki/Political_positions_of_Marine_Le_Pen
It makes sense why the French people are choosing RN—globalization and neoliberalism created a lot of socioeconomic “losers”, and they’re getting their revenge by voting out centrists whose policies are to blame. This is even is clearer looking at the next party that’s winning right now, the leftist and anti-cap socialists.
That embezzlement conviction of Dalongeville, is both damning and an interesting look at the problem. Liberalism and leftism haven’t solved problems that common people actually experience. The right hasn’t either and has no real plan to, they just bother to talk about it and give common people a boogie man that they can aim their anger at.
It is frustrating to me how these parties on left barely even try to make people’s lifes better. To show them why more leftist or socialist policies are the way to go. It has been proven time and time again throughout history that in times of financial insecurity, normal people are easily swayed by far right strongmen and demonization of a weaker other. Why does the left continue to fail at preventing this?
