I suspect it's hard to arrive at any kind of comparison between European and US political systems other than structural comparisons, at least, not in the space available on teh forum. In a sense, although there are specific issues under discussion: the relationship between France and the EU, immigration policy and refugees, the rise of Islamic fundamentalism, Health Care and pensions and so on, the bigger issues are under the surface and here there probably are comparisons to be made. For example, large swathes of the population have not done well economically under the rule of any political party, whereas they see individuals accruing unbelievable wealth. Many are expressing their dissatisfaction in a willingness to consider alternatives, no matter how implausible. This is the background to a Presidential election where all the traditional parties have been knocked out and we see Macron and Le Pen facing each other.
Macron: although it's tempting to see him as a banker, rising to power from the financial sector, he actually spent more time as a Civil Servant and as a Political Party worker for Francois Hollande, the Socialist Party leader. He was a minister for the economy in Hollande's government. He was on the right of the Socialist Party and this is reflected in the policies of his all new En Marche Party, which are all about liberalising (read cutting) laws around worker protection, small government, lower taxes etc.
Le Pen: ah yes, an "old school, traditional, Vive la France type" much in the way that, say, David Duke stands for Truth, Justice and the American Way. Marine was born into the wealthy Le Pen family and is the daughter of Jean-Marie Le Pen, founder of the Front National, a straightforward Fascist Party. After becoming leader, Marine has attempted to distance herself and the party from her father on the grounds that he is a vicious piece of shit, and a Fascist Party rebranded as something less intolerant and authoritarian might be an easier sell. Her policies? Nationalism, anti-immigration, an anti-EU/anti-global stand largely centering on ethnicity.
