I forsee a future where there's an uneasy peace in the Democratic party similar to that which existed during the New Deal days between the Southern faction of the Democratic Party and the rest of the party. The GOP will either die off or fuse with the centrist faction while somewhere down the road (perhaps 5-6 decades from now) the party will split in two.
Wouldn't the fact that the GOP did, in fact, survive that era tend to provide empirical evidence that your hypothetical won't occur?
Possibly. My reasoning is based on the fact that post-millennial Republicans don't consider themselves all that Conservative. Another example here.
The present day GOP is nothing but a combo of racists, religious zealot/nutcases, and true believers of free market Conservatism that was created by historical circumstances that nobody remembers or cares. But this sort of ideology is mostly relegated and propped up by Boomers and older voters. With their political power rapidly declining...the GOP will probably move toward a Phil Scott/Charlie Baker/Larry Hogan RINO type Republicanism which is basically just a dime store Democratic Party.
Another scenario is that the GOP just goes full white power and forever remains the party of angry white grievance but I dont see how this is possible since younger GOP voters dont share their views.
Yeah, this would only happen if those young GOP voters just make their own party to oppose the Dems
