This is not pathetic if you really think about it. Yes, the grovelling appears, at first, a cringe-worthy effort to become the president of a colonial vassal state, but in reality, she got a bag of MAGA memorabilia.
I am sure the red hat is totally worth it.

Less than 24 hours ago, the Trump administration framed a US citizen, a mother, as a terrorist who deserved to die in the hands of ICE. Today, he announced a land intervention in Mexico, and everyone who will die as a result will be presented as a narco-terrorist.

Authoritarianism is boring.
My American friends believe that dictatorships are dramatic with public executions and whatnot. Unlike the movies, dictatorships are unexciting. Life goes on: people get groceries and struggle with bills, as usual.
Losing agency in your own society is mostly boring.
