DJB, this was not the question. It was whether Biden should have the Democratic Nomination. He has decided yes when more than half of Democrats and 70% of voters don't want him to run.
Beginning a campaign with less than half on your side is problematic.
Joe Biden has blocked the way for a younger and more talented candidate for 2024.
Joe Biden doesn't have to be president to stay active and healthy.
I invite you to read "Award Joe Biden with Another Term?"
Many thanks.
