Biden has to willingly step down, the Dem leadership made it clear they won’t attempt to force him. Progressives can’t try to force it either or they will be excised from the party and simultaneously blamed for the inevitable loss.

Biden hasn’t held a full cabinet meeting since last year, so 25th amendment probably not happening either.

And so, ramping up the pressure on Biden to do the right thing by stepping down is the only viable option at this time. It sucks, but this is the bed Biden and the DNC made to lie in.
