From my experience and as someone who knows both American and Japanese internet, what's going on now in the US looks just like what's happened in Japan since Abe. It's strangely very alike. Abe is a literal alt-right emperor, who even likes Putin like those shills here.
The Japanese alt-rights consistently support him despite being poor as shit and on welfare, making shitty political memes with anime girls all day long, bitching shit about foreigners on 2ch and twitter, just like Holla Forumsacks. Abe doesnt directly encourage them, but his party and the conservative/alt-right media often intend to do and pander to them.
As for Trump, as he stated, he will go ahead with some big economic plan like what Abe has done, which is called Abenomics. Contrary on the hopes of your working class and oldies, I bet it will be a pretty half-assed one that only benefits big companies. Those alt-rights will still appreciate it though. They are such people, only want to feel to be part of "the winners" regardless of their real poor social status. Also, Trump is a total amateur politician. All he can do or pretend to work hard is about economy, so he definitely will do this before everything.
And your media will start to pander to Trump. This is what's still ongoing here. You might think it couldn't happen because most American media were actually anti-Trump, are liberal. But I'd say it will happen. The media will dramatically change at a certain point, and go full "We Americans are so great, we are the best country" mode as a whole.
Though I'm starting to doubt if Trump will actually build the wall and deport many immigrants, and willingly cope with complex international issues. Supposing that he learned how to manipulate the supporters and the media, he'd rather set a goal to stabilize his domestic popularity than take an international risk.
Though there's a difference between those, that is, your alt-right emperor is a total amateur politician, whereas ours is a pro politician even though his brain is full of alt-right wet dreams. And Japan has been homogeneous n shiit.
Trump has an extraordinary number of uncertainties. Given that, your country will most likely head for an unknown stagnation, politically and economically, ofc ideologically, that cant be compared with Abenomics and some of his hard-lines and nationalism.
I personally am looking forward to Amerishart horuhoru movement, which is a shameful trend of blatantly and outspokenly jerking off to your own culture, norm, common sense through media and the internet. People, especially those uneducated retards and decrepit boomers, will openly get into how great your country, culture, and people are. And the key point is, in your country, this might be replaced with White people.
Trust me, this will 100% happen.
