Last-day polls for South Carolina were remarkably consistent across the board
Biden: 40ish
Sanders: 24
Steyer: 12
Buttigieg: 11
Warren: 6
Klobuchar: 5
Gabbard: 2
If it ends up like that I think the media will play up Biden's win a lot but everyone else will yawn and move on. If Bernie gets within 10 points than Biden will just be glad he's still alive but will move like a wounded animal and Bernie's folk will consider it a win. If Biden wins by 25 or so, or Bernie finishes in the teens, it'll look like a real win for Biden and there might be some yapping and a bit of a Super Tuesday boost.
If Bernie wins, the race is practically over. Bloomberg will try to make his Super Tuesday run but no chance.
