At this point the 2020 numbers are pretty strongly suggesting a good chunk of Bernie's 2016 support was simply people who hated Hillary. Not only has Bernie not expanded his base, but it has clearly contracted in rural areas and with the white non-college. That to me is the biggest reason Bernie should drop out now, the math is impossible sure, but that was one of his biggest arguments for electability over Biden, that he'd bring those demos with his base.

The other one, his fired up base, also isn't holding up. Bernie isn't driving enough youth and Biden is winning both the rural and white non-college vote, which along with strong suburban performance suggests he's got a pretty formidable base right now. I think a lot of moderate Republicans are more than happy to reboot with Biden in 2020 and hope the party returns from Trumpism for 2024.
