I would add here that the support the GOP gets from “White voters” is non-random. The “White voters” they depend on so heavily are Southerners and Westerners and some Midwesterners.
Yankees are “White voters,” but the Democrats have the Northeast locked up. That’s the base of the Democratic Party.
The GOP can’t reach these voters with racial appeals because Yankees are allied with blacks and support changing the racial demographics of America because it benefits them politically.
Thus, it is easier for the GOP to drive down the non-White vote by downplaying race than it is to win over the White “moderates” in the North by emphasizing racial solidarity:
Note: Surely, Jared knows this living in Northern Virginia which shifted the whole state to Obama for a second time.
If Romney had made a racial electoral appeal to the White working class, he would have lost the NOVA suburbs by even wider margins than he actually did.
