No, The people claiming Trump has huge black support because of the subsection of blacks in Rasmussen are just ignorant of statistics, probabilities and frankly basic math.
A few dozen people, like the subset of blacks in Rasmussen has a huge margin of error.
The most black support a GOP has gotten for President was Reagan in 1980 who got I believe 14%. Trump got 8% in 16. In 20 he will likely do better than 16 but will likely be right in historical norms 10-12%. He may surprise and tie of slightly break Reagan’s 1980 numbers but that would be 15%. Which would be a political earthquake by itself.
Trump is NOT going to get 20, 30 or 40% of thr black vote. If his support in that community were just 20% you would not need a poll to see it, it would be flagrantly obvious on the ground and it’s not.
People need to stop citing sub group breakdowns in larger polls as indicative of those sub groups support the sampling is too small to be meaningful.
When you see a poll of 650 or more blacks nationally that show Trum getting 15% then you have something, but citing some subset of a few dozen or so people as an indicator for the larger group is nonsense
Why doesn’t someone just do a poll of only blacks?
