In all fairness, riding the dementia-addled bastard down in flames is probably the least bad the Dim'Rat paty can suffer for it's short sightedness running Biden in the first place. In that event, all they lose is SpongeBrainShitPants and Kamalatoe Hairs; if they try to bring in a relief pitcher at this late date, they gain nothing (ALL the potential candy-dates poll even worse than #JoeThePedophile against Donaldus Magnus) lose access to Joe's $250 million
war chest slush fund, and smear whatever patsy they run with the same ill favor that colors #JoeTheFraud and Kamalatoe's rejection by the masses. The smart play for them is to let #JoePedo take the "L" while they spend the next 4 years working on their bench.
I got $5 that says the Dim'Rat party doesn't come within 100 meters of the "smart play"...
