We have never seen young people like this, for instance in 1972 with the Vietnam war, the draft, the demonstrations, the anti-war movement and so on, the democrats only got 46% of the under 30 vote.
For Obama, it was 66%.
Obama got 66% of the under 30 vote in 2008. He only got 60% of the under 30 vote in 2012.
Yeah, I know, 60% is still ridiculously high, but at least it is trending in the right direction. Kerry got 54% of the under 30 vote in 2004, so the young and stupid voting mostly Democrat is not an entirely new phenomena.
