Lawrence O'Donell on the topic of replacing Biden as the Democratic nominee (spoiler:
He's against it) It's 27 mins...
However, It's pretty good and raises a lot of points that don't generally get discussed in the context of this particular issue (ie Biden stepping aside). The best point raised, is that the President's main role, ie., making decisions, all happens, by necessity, because of classified information, public perception, etc., out of public view, ie., in private. :
TL;DR - I got you covered, since as I said... its 27 mins... The most interesting point raised was about the money and restriction on campaign spending...
1. Its too late to switch candidates. Campaigns are 4 years long and we are in "the 4th quarter" of "the game" (an American football analogy).
2. Gavin Newsom polls worse against Trump than Biden or Harris, that's why Newsom isn't running.
3. The only way to switch is at the Democratic convention in August. It can't be done now.
4. Every time a switch is done at the convention it results in a loss.
5. The last time Democrats attempted a switch at the convention (1968) it was an unmitigated disaster that resulted in rioting, police brutality, national embarrassment and the Democrats lost the election.
6. Contested conventions get dragged out and the Israel/Palestine issue will look bad for Democrats at the convention the longer it gets dragged out.
7. MONEY!!! Beautiful (campaign) money!! Muahahahaha! By law, no prospective Democratic candidate has any... besides Biden and Harris. (On this point, O'Donnell does concede eventually, that Biden/Harris would likely relinquish their campaign funds to the DNC if they were ousted, thus undermining his entire, otherwise compelling argument about money.)
8. Numerology/Bad Omens.
9. Age doesn't matter, because the Presidency is about making decisions not speeches.
10. The media covers the "theatre" of the Presidency, ie., speeches and gaffes... not the substance, ie., consequential decision-making. Everyone who sees Biden behind the scenes knows that he excels at decision-making (in terms of "sharpness/awareness").
11. FDR was disabled in a wheelchair and still managed to be one of the best Presidents ever, through one of the most difficult times ever. So Biden seeming old/frail should not dissuade peoples' confidence in him.
12. Biden's strength as a POTUS does not and can not get camera-time, because it is not allowed. Jon Stewart's admonition "do we have film?" of Joe Biden being sharp in making decisions, can't be satisfied, because the decisions Joe Biden makes, by law/necessity, must be made privately, as they involve the most sensitive national information, and sensitive political information, that can't be revealed publicly, for various reasons, including political reasons.
