Problem is that going on fox is a direct appeal to people who won't otherwise see dissent or facts -- and Bernie did so well there that it caused a real rift with Trump and Fox so it's hard to see it as anything but a win for Bernie and his stated reason for doing it.
But going on Rogan feeds directly into the 2016 conspiracy and Bernie BroBot atmosphere but without the principled stand our otherwise impossible audience outreach. It's a really bad idea. It will also affect how he's viewed (for better or worse) by regular media. Which will feed into this bad idea cycle.
I dunno, this is a double edge sword.
Positive:
If Bernie gets the nomination its a net positive I think. As it would get some of rogans audience to vote for him, and more so, the bernie bro gans to be talking points in there circles to popularize him more.
Negative
If Bernie doesnt get the nomination its a worse negative. It'll be Nina Turner + Rogans Base turned up to 11 walk out of the DNC, not only protesting the DNC, but the Democratic candidate, pushing your vote doesnt matter furthering voter suppresion, and pushing more people to vote against the Democratic candidate.
For Bernie specifically if he is full bore win it or burn it down mode this makes sense. unfortunately.
At the moment I see the Dem pick being Bernie or Warren, Biden is stabbing himself in the foot repeatedly.
