I'd be curious as of the real reason for the massive right-wing vote of those people. Inheritance tax? Paris-Match+TF1 all day?
They grew up idolising De Gaulle, at a time where the left were evil commies whose tanks were coming from the left, and thus tend to vote to the right.
They are also frightened by crime and violence (that arguably they know mostly thanks to TF1). They also never understood the dislike of "authority" by post-1968 generations. Un roi sans divertissement est un homme plein de misères
