PA is in play b/c the outstanding votes are mail from the big cities so they may well be 80+% Democratic.
Georgia is also a possibility since outstanding votes seem to be Fulton county.
What does jump out is the abject failure of the Democratic left, it's obvious that their only support is in the Democratic party, but their rhetoric tainted Biden with the "socialist" label which hurt him with Independents. If the Democratic left, centered in California, NY and NE, insists on ideological purity in primaries, the Democrats may never be able to become a majority party.
The other problem is pandering, the Democrats haven't figured out that in the age of cellphones, you can't "divide and conquer," that is, efforts to engender support by targeting narrow based issues like BLM backfires not so much due to racism (Trumps' hard core supporters are already there) but by making potential voters feel marginalized - Democrats put so much more effort into courting the black vote that they basically ignored the white and Latino working class votes. And the optics of rioting didn't help with suburban Republican women. Focusing on class (which disproportionately helps Blacks and Latinos) and good government issues (reforming, not defunding, the police) would have sold better.
The second problem with pandering is the Democrats, due to push on the left, end up with policies that are more like a wish list that lacks credibility - we're gonna give you all these goodies but not raise your taxes, we'll just soak the rich - anyone who's been alive the last few decades knows that's not going to happen - so Democrats come off like used car salesmen.
The third problem with pandering is language - you can talk about "rights" until you're blue in the face, but on many issues it's about tradeoffs between personal autonomy and social policies, and most Americans understand balance, but the Left does not - so abortion isn't about a woman's absolute right (the only rights that exist are those provided in the Constitution as amended and interpreted by the Supreme Court, natural rights cut both ways, b/c they imply a higher power granting them, but which higher power?), but the balance between a woman's autonomy and society's interest in preventing infanticide - which is why most Americans come down in the middle. Same with LBTQ and racism - how far can Government go to force people to be tolerant? When you talk in terms of absolutes and political correctness, you raise the spectre of the "nanny" state.
The fourth problem is the lack of charismatic centralist candidates - Obama kicked ass more because he was from Illinois and could talk to middle America than b/c he was Black (I contend that Bill Clinton in many ways was "blacker" than Obama). In the primaries, Biden won b/c he was the only centralist candidate that could garner support, and note that it was Black support that carried him, most of the field veered hard left but the primary voters were more interested in beating Trump than pushing ideology. But Biden isn't exactly a dynamo - too bad Cory Booker is from NJ instead of Ohio. Point is Democrats need charismatic candidates from "fly over" country in their 40s, right now the face of the party looks like happy hour at a nursing facility. If Biden wins but doesn't run for a second term, Kamala may be a disaster, not b/c she's a black/south asian woman, but b/c she veered left and is from California - how will that help in Wisconsin or to flip Georgia? Resentment of patronizing liberal elites is real, and partially deserved - and why the Democrats have to move past their coastal base to be the true majority party.
