The proposed scenario doesn't have to happen.
As it stands right now you have two huge names in media telling their millions of followers that Biden is a bumbling retard and doesn't have the balls to step up.
And Trump's re-tweeting it.
That's massively damaging to an already damaged Biden/Harris ticket.
Besides Rogan, who's the other huge name in media?
I don't watch much in the way of news or podcast type things.
