Because the GOP just doesn't get it. Here in Virginia they say things like "we are the REAL Virginia" which basically means the Virginia outside of NOVA. They aren't even trying to compete for moderate voters anymore. Since when does a national party write off 1/3 of the statewide vote? Especially when they are losing the 20% of voters who are black (who mostly live outside NOVA)...
Well, the national party already writes off blacks, Hispanics, gays, millennials, etc.
They essentially wrote off women too, but luckily for them they still get a large chunk of the white woman Stepford Wives vote, otherwise they'd be in even worse shapen than they already are.
