Forget about Trump...he's just a scary reminder of how many people will still get riled up by xenophobic fear-mongering and aggression, and yeah he's basically the establishment and has been all over traditional media for years.

Bernie, though, I'm pretty sure is a candidate that doesn't get as far as he has without the kind of grassroots campaign only possible in the Internet era. Ron Paul was this candidate in the last election. The Internet definitely has reduced the ability of a centralized minority to control the message, and that will continue as the percentage of internet-savvy people increases.
