Trump getting baited into this one might fuck him if Biden's handlers are smart enough to see it.
The DNC path to victory is to portray Biden as a good man, a long-time legislator who was taken out at the last moment not for his shitty record but for suffering a sad and tragic disease, then throwing in Harris and diversity-ing her to a shock win against a man who was ruthless with an obviously sick person.
A 4-hour Joe Rogan podcast debate gives them just that opportunity. There is no way Biden could make it through such an affair and there is no way Trump could resist attacking him.
If Trump were to be derisive, or callous it could be over for him. Especially if Joe Rogan disapproved of his behaviour at multiple moments, in clips that could be spread all over the internet,
The game with Biden is to trick Trump into being vicious with a man who will be (wrongly) portrayed as a statesman whose mind is failing then throw in the law and order (Indian who they will be portraying as a) black woman.
Something fucky has been going on with Joe Rogan since the Spotify contract was signed. Trump would be well-advised to stay away.
