Today's NYT front page article
on Sanders supporters titled Bernie Sanders and His Internet Army does not appear in any of the front pages of the online "today's paper" editions, the main page or the politics section. I had do a search to find it - and I'm wondering why.
Personally, I think that what they are observing is just the internet itself. Once you get a large enough group of people together - especially a group that has serious grievances - you going to see this sort of thing just because of statistics. I don't think Bernie could say anything to stop it aside from quitting. Which may be what they are trying to achieve.
