My two cents:
We don't need God. The judicial branch will stop the worst you fear from happening, including Trump appointees (and if he appoints dummies and loyalists like you say, it will be that much easier, as shown during his last term). Federalism will also act as a bulwark, along with an independent military, filled with generals at the top who respect civilian rule and democracy. And if this is the biggest threat to the United States, maybe the Dems should move to the middle to stop this and win back the House? That, too, would hobble any bad intentions from Trump.
Does this mean Trump couldn't do damage to the country if determined to do so? Nope. And I agree with you that the worst thing he did while in office was call the election stolen and engage in a Big Lie. But our institutions shut that lie down quickly and absolutely. The odds our democratic institutions will end with a Trump reelection are ridiculously low--think IU winning the National Championship next year in football low.
Our institutions are strong and resilient, as shown by their response to the last Trump administration. They become weakened each time we change their use and our norms to go after one man because we've bought into the hyperbole that he's some kind of mini-Hitler. He's not.
We don’t need God? That’s another thing I don’t get. When did so many of you Pubs (the GOP used to be the party of church-goers and family values) become heathens?
The judicial branch will probably be the only guardrail in a second Trump administration, and I don’t have a lot of confidence in it. Trump has put his own indelible mark on the Supreme Court and will possibly have another appointment in a second term. It is an activist Court that is not particularly enamored of precedent. Clarence Thomas has referred to
stare decisis as just "a mantra when we don't want to think." I'm not sure the Court will have much regard for United States v. Nixon. We'll see.
Further, Trump has made a mockery of our justice system over the years, going back to when he smeared Judge Gonzalo Curiel (born in Indiana) as incapable of being impartial because “he is Mexican.” He’s done a hatchet job on Judge Chutkan, Judge Engoron and others, he’s referred repeatedly to the Special Counsel as deranged, he’s suggested the DA in Georgia is a slut, and he’s called his own Attorney General a “gutless pig.” If Trump is president again and there’s an order or judgment against him, he’ll defy it because there will be no one who will be able to enforce it. Are US Marshals going to come and take him away? Lol. No, he’ll be untouchable. That, in turn, will have a ripple effect on respect for the rule of law throughout his administration and beyond.
Federalism? Trump has no regard for it as evidenced by his interference with state and local elections officials after he lost in 2020.
Our institutions held in late 2020/early 2021 but barely, primarily because Mike Pence refused to cave to the pressure to delay the vote certification and/or send things back to key states for further review and/or the installation of new slates of fake electors. But that was a good dress rehearsal for Trump and the MAGA following. They’ll correct the strategic flaws from 2020/2021 and make it work the next time.
Finally, I’ve never referred to Trump as a “mini-Hitler,” so stop with the over-the-top rhetoric. It is irrefutable, though, that Trump admires dictators and despots, that he believes the rules don’t apply to him, and that he illegally tried to remain in power. That’s a pretty shitty - - and dangerous - - track record. It’ll be exponentially worse in a second term when he’s surrounded by nothing but loyalists, limited guardrails, and with no concern about a reelection campaign. Get ready for “Trump Part II - - - the Chaos and Revenge Regime.”
