This’ll be fun to watch. It’s Bernie Sanders on stage in Philadelphia, speaking to a group of his supporters and attempting to rally them to the side of Hillary Clinton, who he has endorsed. It doesn’t go all that well.

Sanders starts out fine, but when he suggests they come together for Hillary, the boos and jeers get started. Then he attempts to deliver an indictment of Trump, which largely consists of what a bigot he is, because accusing Republicans of racism and bigotry is more or less all that’s left in Democrats’ rhetorical quiver (and it’s something you could actually even make a credible argument for where Trump is concerned) and even that doesn’t work.

There are other videos showing the Sanders gang aping the GOP delegates’ chants of “Lock Her Up!” from last week, which is almost too entertaining to be true.

The Washington Post’s Chris Cilizza is almost despondent about what Sanders’ gang is doing to the Democrats’ convention…

That is an issue for Clinton — and for Sanders. A vocal minority in the context of, say, Sanders’s speech to the convention tonight could be a major problem for party strategists doing everything they can to present a united front. Anything similar to what happened this afternoon — booing when Sanders mentions the need to support Clinton — would be a major embarrassment for the former secretary of state just days before she is set to formally take the reins of the national party.

The scariest thing if you are a member of the Democratic establishment? Not even Bernie Sanders seems to be able to control these people. The revolution is still happening for them, and no one can convince them otherwise.
