Is NBC going to explain this?
I would be interested to hear someone from NBC confirm or deny that this is their reasoning.
It’s not like Warren is left out of the NBC poll entirely. She has the same level of first choice support as Bloomberg, who has no delegates as yet, for instance. But they left her out of the head-to-heads. documentcloud.org/documents/6779…
The release of the DMR Iowa poll was cancelled entirely, remember, when it was learned that one interviewer may have configured the telephone script screen so that one candidate was cut off and thus not mentioned in one question.
