Ironically, the generation that moved the country left in the '60s has been repudiating itself at the ballot box is the same generation that has voted for Republicans 7 times out of 9-- even today polls show that older Americans (60+) are more likely to lean Democrat than baby boomers are.
This is a great point - but I think you're drawing the wrong conclusion. If the '60s generation keeps supporting Republicans it may be more accurate to conclude that a lot of them never were far left. I think the left just makes lots of noise and grabs the most headlines.
I agree with both of your points. Ndog is quite right that there is a misconception about every (or even most) youth in the 1960's being militantly anti-war. They were a minority even at that time.
But Beet is also right in surmising that many youth of the day shifted rightwards (in more ways than one)
later on.
Nor is that confined to the 60's generation.
For as Churchill said, (not exact words) "If you are not a liberal when you are young, You have no heart and if you're not a conservative when older, you have no brain."
I wont go into this in detail but I believe there is a lot of truth in this. I'm only in my early 20's but in my teens I was much more likely to believe in utopian concepts of world peace and redistributing wealth to the poor. As I got older I moved more to the right each year. Hasn't that happened to anyone else?
