This poll does qualify Yang, though (and I think it's the strongest poll he's gotten out of SC, period).

No, Yang still needs one more poll for December.

[Mr. Morden]

If this poll was/is accurate, then Biden would be snagging every state-level delegate in SC.

Except that it has 18% undecided.  If those people either ended up not voting or casting their votes in the same proportion as those who are decided, then that pushes Warren above 15%.
