Sanders has had literally ZERO negative media coverage.
Sorry but that just isn't true and you know it. He's received plenty of negative coverage in recent weeks. Hell, every time there's a debate he gets slammed and Hillary gets praised. He got plenty of negative coverage over the data breach thing too initially but his campaign managed to spin that story around on the DNC rather brilliantly in the end (and nobody is more surprised about that than me).
And while paying a lot of attention to general election polls this far out is silly, Sanders performing like 20 points better or whatever in the two swing states that are paying the most attention to the race so far is definitely kind of interesting if nothing else.
I know you're sort of playing a role here though so do you, my friend...
