The poll is published each day at midnight Pacific Time, so there was time for the speech to have had some effect. Not sure all respondents would have been exposed to the speech, but some could have been. Also note that the point on the chart is an average of the previous 7 days. The daily increase is greater than the average increase.

It looks like a significant move, given the stability of that metric over the past month. Compare with the Hispanic graph, which bounces around and showed a slight decrease yesterday.

It’s time for Dr BEN, Herman Cane and all other Who know the true history of the Republican/democrat party and AFrican Americans to get on the talk shows and educate
ILLarys AMERICA should be promoted again and again. Maybe it could be shown free in inner city theaters for a week

Indeed, I had neglected to take into consideration that the subset poll is also a rolling average. Typed before AM coffee lol.

Considering the above, I suspect that this is a error or they added some new black respondents from a different part of the country. And we don’t know how large the sample of self identified black voters is.

Just a late night WAG, but the 8/16 poll data would have to had approached 40% change among the subgroup to effect that much of a one day swing.
