I really think that for now the government of the USA is in a certain normal degree, if in case Donald Trump wins again I don't know how much he would do, but I think it is not convenient for the world to do it, although there is the possibility that be the best mediator between the war in Russia and Ukraine, it can be a catalyst for many things that happen around the world and that cannot be channeled except with changes of government, in the case of Trump, he will change immigration policies again, eventually He will make it clear that he will make changes in his cabinet or in heads of authorities, and he would totally go nuclear.
The interesting thing, as someone who disliked Trump all his presidency, he sucks and he is bad and I still dislike him but I also come to realization that there aren't any "huge" differences with others neither.
And that is a trouble, if you look at who could be the candidates from the republican side, they all suck, still most have a better face for it, like they are kinder when they talk usually but then go about and do the same thing, so the end result is always the same, and for democrats Biden is kinder and nicer person but then goes and does the same thing mostly. Which means, Trump or someone else, we will have people who will do the same thing, but be nicer about it, and be kinder to people while doing it, not much change in the end result though.
