It can be done with hard evidence. Trump supporters may only need theories and prospects of how it could be stolen, but it will take something more solid for others to be convinced. I was on fire with just the prospects of how 2020 could have been stolen back in early 2021, but by 2022 I was wondering where's the beef myself. Hopefully they have a great list of proven fraud, they have been keeping secret just for the court case, which would make some sense from a legal perspective, but since Trump rarely follows typical legal protocol, and instead just focuses on the political approach, I guess we'll have to see.
Possibly, but my hopes for signs of intelligence among US voters have taken more then one beating. Biden and Fetterman. And others are not that sharp either. I would add, cowardly and greedy GOP politicians. Maybe all I can do is keep trying to convince the others, even facebook fans.
