The timing of the debates would suggest that the Biden team are well aware of the timeline issues and may have just intentionally scheduled the first debate after the Drop Joe drop dead date.
That makes sense. As I see it, the poops have two giant problems.. One is an extreme dearth of talent in the party generally as people like RFKJR and Tulsi Gabbard have walked away calling the party a crime syndicate. The other is that the power of the presidency is the only thing keeping Biden and his entire familly out of prison and I cannot picture him giving it up voluntarily. They’d have to drag his sorry butt out kicking and screaming and the optics of that would be horrific.
The Dems will declare any vote on the Democrats ticket will go to the Democrats running regardless of the name.
