What if America's changing racial mix helps Republicans?

America’s non-Hispanic white population is 197 million, not 2 million more than it was 20 years ago. In the same period, the black population has grown by 7 million, to 41 million, and the Hispanic population has nearly doubled to 60 million.

Conventional wisdom sees this cementing a permanent Democratic majority. I reject this, and not simply because I dislike left-wing government. Nor is it merely because I’m repelled by Democrats’ belief that skin color determines which way people vote. Perhaps the most repugnant assumption of the election was in Joe Biden’s challenge to an African American host: “If you have a problem figuring out whether you’re for me or Trump, then you ain’t black.”
