Speculation is mounting that Joe Biden is being convinced to resign, not just give up seeking a second term. Resigning, rather than just seeing out his term and then stepping down, means Kamala Harris steps up from Vice President. She would then become the first female President of the United States. Also, the first 'woman of colour'.
This makes perfect sense as the Democrats would want to tick this off on their list of achievements, regardless of how the election goes in November. They could appoint Gavin Newsom as her deputy, and the two run against Donald Trump in the election.
If they leave Joe Biden in office, but appoint, say, Gretchen Whitmer as the candidate in November, this has all the wrong optics. It would look as if they prefer not to have a black woman in the Oval Office, which may alienate two groups; blacks and educated women, two core demographics for the party.
Then, even if Kamala Harris loses to Trump, having the right optics may shore up the House race, leaving the House in control of the tyrannical Trump. Also, donor funds would flow, while they're drying up now.
Choosing Kamala Harris as President makes sense, and I'm sure senior figures in the party are going over every permutation while they make their decision.
