If this is the same video I'm thinking of, it was during a debate and he was asked a question about the emails. His response was pretty short, IIRC even Salmongod's short summary is longer than his actual response. He really didn't give a shit about the emails.
Her and Bernie did have about the same platform. For each issue they fell in about the same place on the political spectrum with Bernie being further left. The big difference being attitude. Most US politicians, Hillary included, speak like they're at a job interview. Bernie gave each speech like he was in college and this was the one research project he really cared about. To me and I presume others it felt like he was in touch with the core issues that were important to me, even tho Hillary was on the same side of those issues. The irony of it all is that the differences between the two were things that would only matter to democrats. Hillary wanted the government to provide a social safety net, Bernie wanted the same thing but was willing to change chunks of the government to reduce income inequality. To the Democrats that's a major attitude difference; from a conservative perspective, those are functionally the same thing. Yet independents and conservatives overwhelmingly preferred Bernie. I guess he tapped into that same Trump "better to burn it all" mindset?
