Not to mention, NBC ran the numbers with different turnout cases. In one of those cases, a very realistic but small few percentage point changes in turnout assumptions of different demographics could make the poll swing to 49% Harris to 46% Trump
Further, two other national polls released today showed the race as Harris+3. A lot of the dooming tends to be based on single polls. Yes the polls suggest race is close, but only paying attention to anything bad/mediocre isn't helpful either
