It's not guaranteed, no, and I sincerely doubt we are going to see Trump literally cancel elections, but it's a very reasonable assumption that they are going to do what they've said they'll do and tried to do: install judges that will swing things their ways, suppress voters who don't support them, punish anyone who opposes them, inspire and promote political violence against anyone who opposes them, and gerrymander as much as possible. That's enough to functionally end US democracy if they do it well.
That's not some wild prediction or unlikely outcome, it's the logical continuation of their previous actions. Someone attempting something they tried before isn't unexpected. He actively tried to subvert democracy and the public have rewarded him, why would he not?
That's the key observation.
The logical path here is for red states to cancel elections and appoint electors to send in January 2029. The feds cannot do it themselves, but they do not need to.
The elections clause of the constitution does not apply to presidential elections, and all the constitution says about that is that the states may choose how to appoint electors, as long as it all happens on the same day.
Here is evidence he told the protestors to be peaceful: https://x.com/realDonaldTrump/status/1346912780700577792
He never said "Storm the Capitol!!" or anything like that.
And no, I wouldn't be wrong, because it's a fact he did try to do that, and even if they did—for whatever reason—decide not to try it again, that doesn't change it being what any reasonable person should assume they will do.
The answer to this question is the same as the answer to "what if climate change is a hoax", and that is that I would love to be wrong and would gladly admit it rather than live under a dictator or on a dying planet
If Trump had actually attempted a coup, he would have had no shortage of participants, and they wouldn't have walked into Congress with empty hands.
Jan 6 was very poorly handled. The majority of that is on Trump. Many people - though not even close to "all", or even "most" - present committed crimes. All in all it was on the level of civil disobedience, not revolution.
That time. Neither of us can read the future, here.
