Little understood on FR is that the so called “Progressive Caucus is the caucus of the Democrat Socialists in the House along with Bernie Sanders from the Senate.
Nancy Pelosi belonged to and was an officer in the Progressive Caucus until she decided to go for the Speakership whereupon she disassociated herself from the caucus.
Retired Col./Fmr. congressman Allen West made reference to the caucus saying there were ~80 communists serving in the House. Rep West was targeted, and lost that seat in the next election for letting the cat out of the bag. That was then.
This is now. Trump has driven the commies from cover. They’re out in the open now having lost all sense in their hatred for Trump.
