I just realized I don't think you saw the open letter to Biden that I posted yesterday with an outside-the-box suggestion as to how he might respond to the onslaught of calls for him to step aside. https://marcus17043.medium.com/an-outside-the-box-suggestion-for-biden-6c336f4a9908
If he believes in his heart that he's the person for the job and with the best chance of winning the election, I suggested he could create a win-win by releasing his delegates but not bow out. Go win the nomination at a fair and open convention.
