Its extremely worrying he didnt announce who is replacing him. This election might wnd up being decided by the supreme court after republicans challenge the replacement in the courts
He just gave media something to speculate on for the next couple hours or days. It's much more effective that way because who cares about Trump right now?
Harris had a meeting with the financial backers a few days ago. It would probably be easier for the funds to go to her campaign then if someone fresh started. One of the arguments for Biden to stick around was that the new candidate would have to raise nearly a billion dollars to even have a chance at winning.
Biden’s campaign recently reported $91 million cash on hand. Allied Democratic campaign committees brought the total at his disposal to more than $240 million. Campaign finance experts agree generally that Harris could control all those funds since the campaign was set up in her name as well as Biden’s. If Democrats do nominate someone other than Harris, party accounts could still benefit the nominee, but the Biden-Harris account would have more restrictions. For example, legal experts say it could become an independent expenditure political action committee but not simply transfer its balance to a different nominee.
