I stand that Kamala's best chance is to hold the ship steady as is, and then ask Biden to resign in December or January.
There's a lot of racists out there. I feel like if she's at the top of the ticket, she's gonna get dragged down. Biden truly is serving as an effective shield for her. Either way, Kamala is the implicit vote if anything wrong happens to Biden (which I admit is increasingly likely given his age).
It makes no sense for Kamala to rush to the top of the ticket given her position.
