I don't believe this is going to be the case currently... the trend towards conservative was a fiscal phenomenon, as young kids who didn't have a lot of money and wanted a welfare state grew up and became financially independent, they wanted to keep what they were working to get. This would cause a self centric migration from trending democrat to trending republican.
That isn't how the partisan tribes currently work... They've become more of a "morality" enterprise, on both sides.
The choice is now if you think it's appropriate to ban huck finn and Tom Sawyer for the n word, or ban homosexual references. It's a question of do we spend taxes on blacks and the poor, or do we spend it on cluster bombs for Ukraine.
I don't think people will evolve from one side to the other the way boomers did. I think they're evolving farther from center, on both sides.
I don't like book bans period. I don't like the budget growing exponentially period. I don't like that 99% of the population increasingly wants the other half to be completely discounted... I'm essentially evolving towards not liking anybody at all.
I don't think "liberals" are going to become more "conservative" as they age, because that scale is divorced from party politics. Liberal is no longer a democrat trait, and conservative isn't purely republican. Both have adopted the entire con/lib scale in their own way. Democrats have conservative values, republicans have liberal values (the latter to a far greater degree, but I don't think it matters tbh). Just depends on what issue you're talking about.
It's a question of do we spend taxes on blacks and the poor, or do we spend it on cluster bombs for Ukraine.
I want someone to enlighten me on this, because my impression was that the democrats were the ones on board with bombing for Ukraine and republicans wanted to cut that spending (publicly, cause both parties love that war spending for their buddies to make money from).
