Is there anybody who actually, unironically believes this?
Millenials voted D by 30 in 2018
Yeah, I know. I'm a staunch proponent of the oft-maligned "demographics is destiny" theory because we are currently observing one of the largest generational divides over politics in our nation's history, and the trends are severely bleak for Republicans. But you specifically referenced people who think there won't
ever be a GOP president again after Trump.
Republicans are definitely setting themselves up to be the undisputed minority party on a national scale for an extended period of time in the not too distant future because of this, and Trump will accelerate those trends if the GOP fails to break away from his toxic mold as soon as he leaves office. That happens sometimes in America, with one party being far more dominant than the other, sometimes for several decades on end. But it doesn't stay that way forever. Eventually, the out-party accepts the changes that have occurred and readjusts, and then a new paradigm shift occurs that rescrambles the political landscape.
That's what's going to likely happen to Republicans as the political baton gets passed from the Boomers to younger generations, especially as the Millenials become the most dominant political cohort. Republicans will get locked out of power, will eventually readjust after several cycles, will become competitive on the national stage again, and then a new set of political issues will displace the old fault lines and the coalitions shift.
Anybody who thinks that there will
never be another GOP president after Trump is a fool. If the GOP managed to survive extinction during the New Deal era, this is certainly not going to extinguish them. A
Trumpian GOP, on the other hand, likely has a limited shelf life. It is possible that the GOP won't ever have another president in our lifetimes that adheres to his style due to how untenable it is to the emerging demographic trends and cultural shifts that are occurring within the nation.
