In the aftermath of the mid-term elections Thomas B. Edsall looks at the (continuing) demise of the white Democratic voter.
I added that parenthetical "continuing" since Mr. Edsall has been writing about this sort of thing since at least the early 1990s, when he co-authored a book entitled Chain Reaction: The Impact of Race, Rights, and Taxes on American Politics. I read that book when it first appeared in hardback. Even though it's over twenty years old, it's still as relevant today as it was back then.
