Many polls break national election polling down into White, Black, Hispanic, Asian, and none of those. However Hispanic is treated as an ethnicity on the Census.
In order to get data on the "some other race" category the race and ethnicity question on a poll would likely have the categories (White), (Black), (Asian, Pacific Islander or Native American), or (None of those). I grouped three into the last one because Native Americans and especially Pacific Islanders are too small to poll effectively without huge sample sizes or other techniques.
Have any polls been conducted that tried to measure "some other race" in the United States, in the context of a presidential election or congressional preference (generic ballot) preferably after or during 2016?
Note: this is asked because many Hispanic individuals select different things under the race box and I want to focus on one intriguing category. It also could be used to look at the nonwhite vote excluding white Hispanics. Analysis of Census data shows most who checked some other race selected yes on the separate Hispanic ancestry or origin question. There are also people who choose it who are Arab because the Census says they are white but they often don't identify as such. Leaving Hispanic off a poll would word it like the race question on the Census.
