I agree with you, and I'm reassured to hear your words. I'm not American, so I'm pretty ignorant of the situation but, from my distant vantage point, I found the prospect of Sanders refreshing.
Then I came across articles like the one I posted, and worried that perhaps I'd got it all wrong. But you're right, of course, what I got all wrong was paying too much attention to journalists.
There is a similar situation going on in the UK at the moment for the election of the leader of the Labour Party (Democrats equivalent). It will be interesting to see how both play out.
That's what I think is one of the really interesting aspects of this whole Sanders thing, he's getting barely any positive press coverage. All his hype seems to be spreading by word of mouth and social media. Every article I've read about him is just one person or another complaining about how he can't win and he may screw up the election for Hilary. It really has done a good job of demonstrating how disconnected journalists are from the general public and from the things they report on.
