Some people only care about simple stuff. You know like partying or having fun? US Government being a shit show? War stuff happening halfway across the planet? Some people don't care about that. They don't care if the government they are in is a democracy or a dictatorship. Some people just want to smoke weed everyday, play video games, fish, travel, spend time with family, or get laid... If the current government (whatever shape or form it is) isn't preventing them from doing what it is they want to do, then they don't really care. And reality is, there's a lot of such folks who's pursuits are rather unaffected by the current state of affairs, even if they're large amounts who are. You might think that they should care, and reasonably so, but fact is, some won't until it actually is (too late).

They’re too busy figuring out how to pay their bills to worry about the future of the country.

Some of that base of support already wears lightning stripes. Many other's sport the brown shirts.

Hopefully it doesn't take our cities being bombed into the ground for them to wake up.

That assumes that Trump, Musk and the right wing media won't spin that as Biden's fault, and that Trump is "working on something better". They will, and they will believe him.
