Literally the dems’ only solution to their problem (other than Biden dying) is for them to remove him from office immediately by invoking the 25th Amendment, but none of them wants to assume the responsibility of being the individual to take the lead on doing that because they’re all a bunch of pathetic, spineless cowards.
There’s a theory going around that they’ve resigned themselves to losing to Trump this time and, rather than “waste” a “better” candidate, they’ll just let Sloppy Joe limp to defeat and blame their loss on him, rather than their policies.
And it would be an admission on their part they know now, and knew for a long time, that Biden was a cognitive mess.
All they need to do is get Biden to sign an assassination order for Biden.
He'd do it, since this would be the second assassination order he signed this month alone.
