Regardless of if he wins or not, his party and movement won’t survive him right? Isn’t that always the case with personality parties? I can’t think of a personality party that outlasted the person. Help me find an example...
The bigger question here would be, which party takes its place? The National Front de facto replaced Les Republicans as major force on the right side of the political spectrum. On the left, the Hollande's PS is de facto dead. The far-left alone is too weak for majority as well. Maybe the Greens? France is a prime example how the main political conflict is no longer between social democracy and classical conservatism, but has shifted to globalism vs. nationalism.
