I'm from the UK, so don't have the best optics on US politics, but Biden strikes me as quite conservative, probably leaning middle-right. I would guess that Biden would be "more of the same" as pre-Trump - probably a welcome relief after the madness of Trump, but many will not welcome a return to the status quo.
That sounds about right. We'll have to see how much pull the more liberal dems have on him, the impact of AOC/Warren/Harris especially. The republicans are saying Harris is more liberal than the whole senate, but I don't see that. Time will tell. Warren was who I wanted.
