I actually think he has an interesting point here:
Which I've sort of been annoyed with (and have stated here before) that the term "establishment" now just means "Not Bernie", as evidenced by the handwringing over the HRC and PP endorsement versus other labor unions.
Is it a good idea to attack Bernie? Meh, it's Bubba, and I think that he's more charismatic than anyone else in this race at the moment and can probably get away with it. I also think he's right that the harassment that supporters of Clinton have faced on social media has been striking (don't tell Glenn Greenwald that, because people are mean and something about how all campaigns do it and idk idk)
