Like it or not, two party duopolies are the norm in developed countries. The only effective approach is to reform the GOP.
The GOP was borne out of the Whigs, which fell apart over issues similar to what we see the GOPeRINOs falling for.
Just because it’s the norm doesn’t mean that it has to be that way, anyways.
The GOP didn’t reform the Whigs, they replaced them. That’s what the Social Conservative America First Constitutionalists should do.
