I hate how accurate this is.
You have to step back and realize that when you're claiming the only accurate media is random outlets on Youtube, you've gone a bit far. We'd be blasting people on the right if they said these arguments about the media treating their chosed candidates. Cruz does it all the time, and it's batshit crazy.
Also, the reason Bernie isn't getting coverage is because he's not doing well now, and he's starved for air time thanks to Trump saying newsworthy things every week. Hop into Poligaf threads from a few months ago, and the constant conversation was about what Trump would say on Friday to dominate the weekend news. He knows how to get the headlines, and the media isn't wrong for giving him that. He says new things every week, and they're crazy as shit. That's news. Bernie almost never does anything new, which is why you have places like CNN cutting away from his speeches when he starts pulling a Rubio, to put it bluntly. It's not interesting to most readers/viewers since it's old news.
And this interview is a softball at best. Bernie should've walked into this thinking "I'm going to knock this out of the park, and it'll drive a 'Bernie's serious business' narrative." Instead, he legitimately comes off like one of my students who clearly decided to wing the day's work instead of preparing something. The words "pie-in-the-sky" have been attached to him for a little while, but that's not a good thing if it sticks around. By that, I mean it's one of those qualifiers that starts as a compliment (He's a dreamer!) that eventually morphs into a negative (He's unqualified!).
Like someone mentioned, it only gets worse if you're the nominee. Much, much, much worse. The Republicans had Hillary Clinton sit through over 10 hours of needless interrogation for the explicitly stated purpose (thanks McCarthy!) of hurting her politically. If Bernie has trouble with interviews like this, where it's honestly a great chance for him to stay on message if he wants to, then he'll get annihilated publicly for months in the general. He needs to do better in this environment.
I'll say this; he's had few opportunities to practice this because New York is just that different. The media market there is another world to any primary before now, so it's understandable that he's green to it. But them's the breaks, as the youths say.
