It's early and it'll be interesting to see what it looks like when we get a fuller set of data from some higher-quality pollsters, but I'd say Biden is holding up better in the south than I would have guessed based on the higher-quality national polls
The Quinnipiac poll, for instance, had Biden at 27% among black voters. I'd guess he does better among southern black voters than all black voters, but that was before NH, too; I thought there was a real shot he'd be at <25% in SC/GA, and--*so far*--he's holding up better...
At the same time, you've got to wonder about whether it's durable. He's at an acute spending disadvantage in the Super Tues. states; we know his support faded at the end in IA/NH, as voters tuned in. And weeks of dismissive coverage could take a toll, too.
One thing that he does have going for him is that the primary electorate in a lot of these Southern states tends to be older than NH, let alone IA. If his IA fade wasn't a real fade but a product of the weird LV universe, as our poll suggests, then maybe he holds up a bit more
A related, interesting question is whether a Biden comeback in SC would be good or bad for Sanders. It's hinges on two other questions: how strong would Bloomberg be if Biden gtfo; could Biden turn SC into a viable comeback, given his $ and how close SC is to Super Tues?
My instinct is that the answer is 'stronger than a divided opposition, at least' and 'no.' But this is like trying to think 10 moves ahead in chess (i don't play chess so don't get pedantic with me, chess fans) and we'll see what the board looks like when we get there
