Polling seems somewhat mixed still, given the last week.
Democratic Derangement Syndrome is real, and we shouldn't act like the media is some independent actor who is "just reporting on what everyone knows". They just constantly love to push "dems in disarray" style stories, because that's what draws clicks, and some people latch onto those self-destructive stories like lampreys. Candidates certainly matter, and Harris could be a better choice. But the way forward, regardless of the path selected, is far from clear, and the media will continue to do what it does.
