Demographics favor Democrats. Period.

Ya want a single fact to "take to the bank" as to why the Republicans should be really worried about their future as a national party?  It's this: the highest percentage of voters under 29 voted Democratic in 2022 than in any election in over 50 years, and the highest percentage of them voted period over the same time. First time voters tend to vote again, and more often than not for the same party as the first time. Go figure: Democrats' share of the electorate is increasing; Republicans' is decreasing. The outcome of that process over even a few election cycles, with the electorate even in many "red states" close to evenly divided, is obvious.
