I've thought from the start that it'll be Kamala Harris, and I still think so. This'll make the ticket even worse, since she's an authoritarian neoliberal who only cares about power.
Kamala Harris hopped on the "Defund the police" bandwagon and is applauding Eric Garcetti's decision to defund the LAPD.
https://thehill.com/homenews/campaign/502187-harris-grapples-with-defund-the-police-movement-amid-veep-talkDefunding the police is wildly unpopular among anyone that isn't on the far left because of the contradictory notion of wanting better trained police officers and decreasing resources to get better trained officers. Kamala Harris switches her position on whatever's popular at the time and its obnoxious. I fully expect a walk back from this when it comes November.
[Pelosi is not in charge of presidential politics, she is only in charge of Congress. If Democrats win both the presidency and the Senate, I would expect the Supreme Court to get packed, and for fair elections to be removed.
True, but it goes to show you that there is tension between establishment democrats in shifting the party further to the left. If a democrat were to win, the house majority leader would definitely become involved in the executive branch in coordinating legislation. Biden could adopt leftist policies but I think his administration would be Obama 2.0 (unless he gets completely hounded by the left).
