People talking about demographics have the wrong end of the stick. White conservatives don't vote for white conservative candidates because they're white, they vote for them because white supremacy is at the core of American conservatism. So long as Republicans continue to embrace distrust and fear of non-white people and of women, they will continue to lose those constituencies. It's possible conservatives can change (although I don't see how), so this problem is fixable. And I hope they do fix it, because we'd all be better off if the Confederacy finally accepted defeat.
