People like Trump do not experience shame and are not deterred by obstacles. The Trumpists will not share your calculations that their efforts are unlikely to succeed and give up pre-emptively; they will try many things all at once and shift to new options if their initial efforts don’t work.
The January 6 coup attempt was premised on absurd readings of US political processes and was unlikely to succeed *and they did it anyway*. Real people actually died as a result. The coup attempt failed because people in power actively chose to resist and sideline Trump, and not because “the law” is somehow self-executing. And, despite failing, *Trump is president again*.
