But the race wont' be won by winning over these groups; it'll be won by winning over better-educated, better-off, younger urban men and women and by increasing turnout among traditional left-voting but lazy (in 02) constituencies among students, teachers, civil servants.
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
