I mean the US is a deeply patriarchal society that has normalized and enabled abusive patriarchs in the homes. It stands to reason that the highest office in the US is a reflection of what its people view as the position of father.
It's not unique to Trump, but it's certainly the most open-faced. His supporters go on like insufferable kids, trying to stay on his good side and celebrating him for enabling their worst impulses.
But the libs have done it too, Daddy Biden, Daddy Cuomo, Tim Waltz, etc. Even Kamala had maternal traits imposed onto her, but only in relation to her running mate being coded as a father.
There's some serious pathology going on in the US. Shit sucks.
