Most conservatives understand that the point of the Declaration of Independence and the Constitution (as amended) is to apply all principles to each and every person individually regardless of race, creed, color...etc.
The political advantage of this is that these principles do, in fact, cross racial and other group lines. The strength of the Constitution is what conservatives have - every single person is a minority of one and so is equally protected by our Constitution and our laws.
The rest is race/gender/whatever group baiting at best. We teach conservative principles to everyone, we end up with a majority of voters.
I’m no fan of identity politics myself.
But it is a useful tool that the other side uses. And I see no reason for the GOP to unilaterally disarm itself.
I still don’t see why it is racist to target white voters and maximize their turnout.
