Much has been made about Bernie Sander's popularity with the younger voters, 18-29 year olds. Many of these people are very idealistic, others lacking of political history (which is pretty easy to get online tho), many are both. Every election or two, someone who is going to change politics and end partisanship comes along on a white horse or white horse-like animal that shits rainbow. Obama is kind of guilty of this, of course, if you really bought it, not that I did in the 2008 primary.
I am a millennial. I was born in the latter half of the 1980s, have barely consciously known a world without the internet, never was alive in a country which in my lifetime banned people voting, living, marrying on the basis of skin color, and so on. However, because I've been following politics since I've been in high school, and first closely followed a campaign in 2004, after kind of knowing ones were happening in 1996 and 2000, I took the time to learn history, which is reflected in many of my posts. It's readily available via online archives, which is why I don't buy the excuses out there about not knowing how different times once were, or how public opinion once was.
