Had to turn that off, struggle watch Trump at the best of times but what they are doing with Biden is just deeply irresponsible. His issues are clear to see and the fact they seem to keep him performing purely with medication is morally wrong.
See a lot of people asking why they don't focus on the Trump being a felon issue, it is very unsteady ground in my opinion. Aside from there being many who question the proceedings due to a perceived impartiality, if they do focus heavily on this they open themselves up big time to the Hunter issues, for which there is a risk that the "smoke" his other shenanigans involve Joe will come up and be a problem. Dems need no convincing on the felony, Reps don't care and the undecided are probably split. The risk is Hunters issues and the link to Joe, unproven or not, can create as much noise as the Trump felony (rightly or wrongly, I'm just speculating here). The Dems will want to avoid this since the Trump felony is known and I don't think they gain anything by pushing on it.
With regards to Newsome, again I would imagine all Dems would support him (including the left), but is he going to sway the undecided. Do the undecided, and America in general, want "California" for the whole country? I think California is a potential negative for him on a national stage.
Clinton - just no, she is toxic. She has also spent a lot of time denying/disputing the 2016 result and she is an easy target to be dubbed an election denier herself, again not amongst the Dems, but the undecided.
I genuinely think this is a golden opportunity for the Dems, Joe can pull out for health reasons, tearful speech, portray him as a retiring American hero then ride the wave of goodwill with a new candidate who will honour his legacy, consult him on a handover etc etc. If it is managed properly I think the sympathy will offset a lot of the mockery/negativity from the Republicans. They absolutely have to have a new candidate in my opinion.
