I seem to remember seeing that in Italy, PD actually does best among the oldest age groups, which is pretty unique for left-wing parties.
In Austria too: The SPÖ sucks among young people and does best with old, retired folks.
Other than that, our voting trends the last year pretty much looked like the ones in the US: a huge urban/rural divide between Left and Right and educational gap. Hofer did best with taxpaying (working-class) people in the labour force, whereas young people and retired people backed VdB by bigger margins.
