The Southern Strategy in a nutshell
From now on, the Republicans are never going to get more than 10 to 20 percent of the Negro vote and they don't need any more than that...but Republicans would be shortsighted if they weakened enforcement of the Voting Rights Act. The more Negroes who register as Democrats in the South, the sooner the Negrophobe whites will quit the Democrats and become Republicans. That's where the votes are. Without that prodding from the blacks, the whites will backslide into their old comfortable arrangement with the local Democrats.
Kevin Phillips 1970 New York Times article
Now it has been expanded to a national strategy with added wingnutty goodness:
Replace "negrophobe" with, racist, sexist, talibangelicals, islamaphobes, bigots, and gun nuts [and any more you care to think of].
Add to African Americans:
Women
Native Americans
Hispanics etc etc etc.
The LGBT Community.
Non Christian Religions especially Islam
So the new national strategy reads something along the lines
From now on, the Republicans are never going to get more than 10 to 20 percent of the sane vote and they don't need any more than that...but Republicans would be shortsighted if they didn't try to overturn the Voting Rights Act and generate fear and loathing. The more women, people of color, gays lesbians, heathens who register as Democrats in the South, the sooner the bigoted whites will quit the Democrats and become Republicans. That's where the votes are. Without that prodding from the women, people of color, gays, lesbians, transgender, and heathens the hate filled will backslide into their old comfortable arrangement with the local Democrats.
