i think its more of a face saving lie that mcmorrow dropped out over the twitter poll.
she ruined her campaign by trying to make it about hasan piker, who wasnt running, and a good portion of the people she needed as supporters kinda like piker on at least a surface check of what he has to say.
i think more what happened is all her donors were already out, and they just pointed at that poll. its not like it was a unique poll.
pointing at the fake poll gets her(and her consultants) some cover for having made bad campaign choices
