I would like for them to split off from the party and start a new movement dedicated to fighting for the people. They have the influence to start a way stronger 3rd party than modern is politics has ever seen.
At bare minimum, they should band together as a new sect of the Democratic Party and establish that their ring of the party advocates for people instead of oligarchs.
lol I still would rather they just start a third party, but maybe I could get behind Guillotine Democrats
