Friend of mine is friends with a fairly recently departed staffer for our local Congressman...
Remember, this is third hand, but it jives with some other stuff that's coming out...
The indications are that the squad has a small group of fairly core supporters, but by and large they're pissing off a LOT more of the caucus than they're winning over, including people who are a lot more influential and a lot more powerful, but who don't get all of the sparkly press. They're looking to put them on a VERY short chain.
That explosion by Virginia's Abby Spanberger last month was apparently the public tip of a very deep iceberg.
Personally, I hope to hell that they try to muzzle them, but fail miserably, because I want to see Spanberger's predictions come true.
