Yes, but Trump won a majority of White Women, and there were over 9 million people who voted for Obama who switched and voted for Trump.
So you are accusing millions of Obama voters of being racists? Really? What about the alternative that your reductionist identity politics analysis is wrong. Also you try to dismiss Trump’s Blue Collar support. But if you took a drive through Western Pennsylvania or Ohio or Michigan in 2016, it was more than clear Trump had a lot of support among industrial, construction, and trade workers.
More recently Trump’s approval rating from Black Americans has risen dramatically and his support among Hispanics exceeds 40%.
