The GOP may not even exist by then, or at least be a viable party at that point.
In the 1984 Canadian election the historic Progressive Conservative Party swept to power in a historic landslide. 4 years later they had started to irritate their core voters, but were able to win another majority running in a single issue - Free Trade with America. They immediately went back to abandoning their core voters on social and constitutional issues (appeasement of Quebec separatism). In 1993 they were reduced to 2 seats in the entire country. A western party (think the Deep South) wiped out the Conservatives and cost them almost every other seat. All through this the Conservatives had arrogantly stated that their voters “have nowhere else to go” and would slavishly continue voting for them.
The GOP. and it’s core voters are at this same crosswords. They are abandoning and denigrating the man who was chosen and elected by the base, and were complicit with the Dems on delaying or stopping his ability to fulfill his promises. The GOP has given the big FU to its core voters. They will not change. They must be destroyed.
