Right…the primaries. Like when Jessica Cisneros ran in Texas, and Pelosi backed Henry Cuellar instead (voted with Trump >80% of the time) and poured tens of millions of DNC money into that race to ensure the progressive Cisneros lost.
Or perhaps more recently, when the DNC anointed candidates for the presidential nomination TWICE without holding a primary election in good faith. Then lost in spectacular fashion.
Establishment dems don’t play fair when they get challenged from the left, hell they completely throw democracy out the window when that happens. The party is lost and the real “Republican agents” are the ones saying “no no, keep voting blue you can change the party from within!” It’s a fool’s errand.
