It’s really up to what people do before God as to whether that happens, or whether GOP returns in sincere hearts to the best of its ideals. Which are nothing to sneeze at.
The founders saw the formation of parties early on, and also despised them and inveighed, in vain, against them. Presidential elections were envisioned as being about the person. They’ve almost all turned out to be about the party. Donald Trump is an exception, and he chose the GOP because that was the less bad of the two major horses to ride.
What evolves from here, truly only God knows. I don’t care what they call a rose, however, as long as it smells sweet.
