This is from a conversation between Bill Kristol and James Carville before the Primary last week. Although Carville's comments are specific here to "The Squad", I think it in encompasses all who are on that wing of the party, including those who protested yesterday.
JAMES CARVILLE:
...There’s a big event today in the Democratic Party. Huge. That is the primary election in the first Congressional district of Missouri, think of it as St. Louis, where you have the ultimate, what I’d call “squadette” or whatever in Cori Bush. They are—Mark Mellman and them—and she’s of course, let’s just say she’s very pro-Palestinian, to put it at that, but it’s an understatement.
She’s running against a guy named Wesley Bell, who’s actually a prosecutor, and describes himself as a Black liberal. Remember that used scare people now. Oh, Jesus Christ. Yes, of course. Come on in. They put a bunch of money in there, but they’re running a really smart campaign, all right? They’re not running it. He’s got good consultants. They’re talking about she voted against the Infrastructure bill. One of 10 people. I hope I’m right, but I think Bell’s going to win and tomorrow, I will be commenting on it.
BILL KRISTOL:
That would be the second person in the squad to be defeated and I think in both cases, the campaigns… Even though a lot of people were interested in it, probably because of Middle East politics and other stuff, the actual messaging of the campaign was more about just not being a radical obstructionist really, and being a mainstream liberal.
JAMES CARVILLE:
These people have literally been… Not only are they wrong about everything, they destroy everything...
