Replacing the Potato is effectively tacit admission they are giving up on the White House and are trying to prevent a down ballot massacre.
For someone to drop in 120is days out and be able to win, would require a superstar, and not just a superstar but a superstar’s superstar… there is no on on the Dems bench who can fit that mold. If there was they would have run them in the first place.
They have people on their bench who can motivate their base better than the Potato, just run a radical leftist and they will fire up their base, but no one who can do that and win the middle, and they know it.
So replacing Potato is effectively tacit admission the WH is lost and they are desperate to motivate their base in order to not get wiped out downballot.
I’m going to hope and pray that you’re right but work like you’re wrong.
