Dordogne, Correze, Vendee, Ariege, Hautes-Pyrenees, Creuse, Haute-Vienne, Indre, Haute-Saone, Var (to an extent), Aveyron, Lozere (to an extent), Ardennes, Vaucluse, Herault, Gard (both to a limited extent), Lot; even Cantal, Puy-de-Dome, Pyrenees-Atlantiques, Pyrenees-Orientales and Charente don't exist guys? I'm not saying this is the cause of anything or that it explains all much or that the correlation is even strong; but denying that there's just no connection is stupid. And I hope you're just denying the link in a modern context; because if you're denying the existence of any link, ever; you don't understand French history. Certainly the connection is much, much weaker now and isn't a good explanation for modern stuff, but...
But what political correlation are you talking about ? What's connexion between normandy, Alpes, Pyrenees, Ardenne, Dordogne, Corse, Upper Languedoc ?
leftism ? no (normandy, Alpes)
rightism ? no (upper languedoc, dordogne, pyrenees)
catholicism ? no (normandy, dordogne, upper languedoc)
protestantism ? no (corse, alpes, ardennes)
centrism ? communism ? far-right ?
I search this relation, but I don't find it anywere
