When looking at US midterm election statistics

White, Black, and Latino are always there,
but Asia is never included lol
Looking at local posts discussing those statistics,
it naturally seems like there is little interest in Asians.
I wonder if this is due to discrimination,
if it's because the population is that small,
if it's because of a tendency not to clash with locals which leads to lower visibility,
or if there is some other reason.
