co-sign but i will add: i don't know the best path but i do know the worst path, and that's replacing him with anyone other than kamala, via any process whatsoever.
I have no idea the best path re Biden but I do know a solid week straight of “Biden Old” and “Rich Dems Worried” above-the-fold stories are *obscene* in the face of SCOTUS using the Constitution to wipe their asses purely in the service of reinstating a felon rapist as president. Crazy-making shit.
I know the best path: Make Kamala the first woman President of the United States. Now. Joe can do that with the best speech of his career and then ride into the sunset. Make a big show of it. Pomp and circumstance. Then Kamala picks Whitmer as VP and they run as incumbents.
Sorry but you're doing vibes based electioneering. Harris stacks up to Trump right now within MOE without even being the main nominee. All of his strengths and none of his weaknesses (his visible age).
Even a small bump matters in NV, AZ, GA, PA, MI, and WI, all tossups right now.
