Kamala Harris has enjoyed renewed attention as speculation mounts that Biden will step down in the aftermath of his disastrous debate performance. Betting markets think that Kamala Harris will be nominated; the DNC has run fundraising ads with Kamala; and black congressional leaders have made it very clear that if Biden steps down, there will be hell to pay if Kamala is passed over. After a brief lull in the immediate aftermath of an assassination attempt on Trump, anti-Biden forces within the Democrat party redoubled their efforts on the last night of the RNC convention, leaking unconfirmed reports suggesting that Chuck Schumer, Pelosi, and even Obama have tried to convince him to step down.
