First off, I guess I'd have to ask if there are any true, old-fashioned "young Republicans" left to be found anywhere? You know, the kind who would support Nixon, Bush, McCain, Mitt Romney if they were running today? The only "young Republicans" that I know now call themselves Independents and mostly support either President Trump or Governor DeSantis and not too many others.
The old, traditional Republican party is long dead. It is no match these days for filthy corrupt, dishonest, well-funded election-cheating power of the DimocRATS. Even conservative old moi is registered as Independent. So who the Hell are Politico and Harvard talking about? I have no idea.
