Political parties in the US aren’t monolithic entities that never change or shift positions. Every 30 or 40 years they change and factions can switch sides. The southern strategy saw “Dixiecrats” become Republicans in the 70s and 80s.
Ross Perot won approximately 18 percent of the popular vote in 1992. Once again, parties shifted their policies and absorbed those voters.
I think we are overdue for another major shift and possibly a third party run. Many “Moderate” Republicans are Republicans in name only at this point. Their party has been co-opted by Racists, secessionists, MAGA, Qanon, Evangelicals and other fringe elements. (Whom they freely courted in the past and viewed as useful idiots to further their own goals.)
The business community, fiscal conservatives, NeoCons and moderates aren’t used to being out of power. They are organized and have money. Their goals overlap more than MAGAs. It’s only a matter of time before they realize they no longer control the Republican Party and may never control it again.
If Trump or MAGA acolytes stay in power after 2024 you will probably see a significant fracturing of the Republican Party.
