How will we prevent this, or cope with it if they succeed?

Because if they succeed, you should leave. I’ve already told my family, if Trump wins, I will come back right after the elections to get the rest of my personal stuff and then my sister and brother in law need to prepare to leave the country. They are too politically astute and active to stay. The rest of my family should be okay if they keep their heads down.
Except that many are either mixed race or LGBTQ.
But I will not step foot in the US again.
Chile or Argentine are probably the best examples to look into.
Watch Nostalgia for the Light to see what happens (brilliant film on numerous levels).

The red tape involving the target country ALONE is enormous, not to mention what kinds of restrictions the (once great) USA will impose!

Generally, you need to have a certain skill that they need or enough money to support yourself (millions in the bank). Of course one could go to a third world country a lot easier but that might not be any better than the US.

Granted I have no kids, so nothing tethering me to the US. I’m highly educated, but had to take a crappy paying job to get here.
You do what you have to 🤷🏻?♀️

I have a problem with that.

I'd like to tell them where they can stick their dictatorship.

Göring: Why, of course, the people don't want war. Why would some poor slob on a farm want to risk his life in a war when the best that he can get out of it is to come back to his farm in one piece? Naturally, the common people don't want war; neither in Russia nor in England nor in America, nor for that matter in Germany. That is understood. But, after all, it is the leaders of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy or a fascist dictatorship or a Parliament or a Communist dictatorship.

Gilbert: There is one difference. In a democracy, the people have some say in the matter through their elected representatives, and in the United States only Congress can declare wars.

Göring: Oh, that is all well and good, but, voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same way in any country.. Dr. G.M.

"The people" don't know what they want until we're told when, where, and how to think. Don't think for one second Democrats, independents and so called "L"ibertarians are immune; "Lock Her UP!" If it weren't for the independents and "L"ibertarians being such useful idiots in every presidential election, we might have had some governance for "We, the People." Instead we had minimum 50 years of being pissed on and told to pull up our boot straps.

like a strong man who takes charge.

they're too stupid to realize that the person who interprets the ideology isn't god, but a human, and that no one ever agrees about religion. Our founders knew that, and so separated law and religion.

would be a piss-poor choice to ever lead ANYONE in a theocracy. Bet that fkr doesn't even know The Lord's Prayer.

Trump is a con man and a user and doesn't matter to him what or WHO He uses: the flag, patriotism, Black folk, religion, the Bible, even God, to further his own EVIL ambitions..
