There were lots of young folks like clintons, Gary Hart and Tom Daschle that supported McGovern. The whole anti Vietnam crowd supported him very enthusiastically. He was a WWII war hero though he never made much of it.
We will see what happens. The future is not ours to see.
I have to say that the historical comparison between 1972 and 2008 are almost nonexistant other than there being a democrat, a republican, and a war.
