14. The 90/10 categories are often difficult to capture in polling

I have noted that for decades. The numbers are so small that all it takes is an odd sampling to throw things out of whack. If you look at crosstabs sometimes it can literally be 10 people skewing things, like a Hispanic sampling in some state that is only 6% Hispanic and among a sample of 1000 voters the Hispanics are 30-30 instead of a more logical 40-20. Now it's 50% instead of 67% and everybody freaks out wondering how Hispanics can be 50-50.

I always ignore the partisan and Africian-American polling percentage and assign the standard 90/10. Trump received 8% on the black vote according to the 2016 national exit poll, and likewise 8% of the Democratic vote
