It is probably apt to call her a fascist. Fascism is not inherently anti-semetic, and a lot of her economic positions that I’ve heard of sound like she’s for Italian corporatism 2.0.
She isn’t opposed to the idea that the government heavily intervenes in the market, just how it is being currently used. So she thinks that price setting, wage controls, import controls, banning or restricting foreign ownership of companies, ect, are all well and good. She’s against the privatization of government industries, increasing the age of retirement above 60 years, and so on. Just because someone is opposed to socialists or Muslim immigration hardly makes them conservative in the American sense.
But unlike many others, including Sarkozy and Hollande, she is a nationalist who doesn't share the unvarnished support of the EU and integration of Europe. Who can blame her? The EU was really driven by the French, but German economic power is now driving the train. She wants control over the currency and national trade policies. She also wants to limit immigration, which is destroying the country in much the same way that it is doing in the US. At least, she understands that France is in a battle for its national survival.
