Democrats almost never care enough about their cronies to primary them out. Only rare upsets (Crowley) or defectors on important issues (Lipinski) get the boot. The Dems also never seem to retire, which is why their entire leadership class in Congress is approaching 80 or older. In general, only the Bernie Bro wing of the party seems to care enough to primary people and put pressure on their incumbents, and even organizations like the Justice Dems have been turned into a joke by supporting people like Neera Tanden.
Tanden was/is a Clintonite DNC hack. She attacked Sanders and the left flank of the party viciously. But before her name was withdrawn for OMB, the head of Justice Dems, Alexandra Rojas, supported her confirmation.
More broadly, the whole squad stopped standing up to Pelosi on important votes post-2020 when their House majority got diminished and they 'needed' to fall in line.
The squad in 2020: "Defund the police!"
The squad in 2021: "Just enough of us are going to vote present for this $2 billion for capitol police to pass"
