Yes, and if I'm reading it right, Trump is going to keep hold of the Republican party, meaning the impeachment trial is likely to fail, but hopefully the ban on holding office in the future will take effect.
I get the impression that Trump has shown Republican members of Congress how strong his hold on Republican voters is, meaning his threat to start the Patriot Party has teeth. The Republican members of Congress consequently fold as they did during Trump's Presidency because they know he can end their political careers if they don't toe his line. I therefore suspect the trial vote in the Senate will be similar to the last impeachment.
So even if Trump can't be a Presidential candidate in the future, he'll have a lot of influence in choosing the 2024 candidate.
It's interesting to contemplate how much influence he'll retain if he somehow ends up in jail.
The Republican Party created its own monsters, first by not reining in the Tea Party candidates, and then allowing Trump to abuse the power of the office to run roughshod over Congress. They are far from the party of Reagan, and equally far from the ideals of the GOP. And the few that did stand up to him (e.g. Flake) were either cast aside or did so too late, such as when they were already heading out the door.
If Trump decides to create his own party, I think that can actually be a very good thing, assuming that the more reasonable members of the Republican Party use the opportunity to reorganize and get back to what they traditionally have believed in and done. They can show the radicals like Marjorie Taylor Greene to be the dangerous nutjobs they are, and start to bring some sanity back to that party.
That said, I also think that the Democrats have completely screwed things up in many ways, and have made it more likely for Trump to keep more power than he should. They should have waited a few months before delivering the articles of impeachment to the Senate, and instead worked on a reasonable agenda to begin to bring things back toward the middle. By putting Trump on the sidelines while actual progress was made, he would be shown to be less important. Instead the trial has much less chance of succeeding, feels rushed to many, and will be trumpeted as a vindication by Trump and his supporters if it goes the way it seems likely to. If they had instead worked with those on the right, many who are afraid of the 'evil socialist agenda of the liberals' would be put at least somewhat at ease, and therefore they wouldn't automatically cling to Trump and his craziness.
I also think that President Biden should have, instead of flat-out canceling Keystone, put it on hold for a period of X days, while alternatives can be investigated. Even if the ultimate decision would then have been to cancel the project, the workers would have felt more heard, and he would have been seen as looking for reasonable solutions that can address everyone's concerns. Instead the decision can be seen as knee-jerk anti-oil and oil workers.
