I would probably regret it, but I would be curious to talk to some of these young people about why they like Bernie so much. I can't imagine that when I was in my late teens and 20s I would be going with the old white socialist over Hillary. Obama I get. Heck, I was won over by Obama and I was in my mid 30's at the time. But I've found Hillary to be a lot more likable since then.
Young Democrats are more amenable to social democracy and socialism over capitalism because of the economic collapse.
