As a millennial 30-something, my ilk are only slightly left of the older generation. Gen Z, of which I have some (in-law) siblings, is different. These are kids who saw the Trump shit, even if they didn’t totally understand it all. But it left an impression. They are also way more open minded and waaaay less religious. That alone indicates a shift left. And the old adage of shifting right in your 30s/40s has not held for millennials. Assuming it doesn’t hold for Gen X (why would it?), the US is going in a promising direction.
One problem we do have is an activation of boomer voters in response to this stuff. But y’know what Gen X has that Boomers don’t? Time.
