Which is the tell that Trump didn’t believe his own claims of vote fraud. Bear in mind he pulled exactly the same stunt in 2016 claiming massive vote fraud but when he won never mentioned it again until 2020.
If he’d actually believed there was vote fraud or a chance of it, he would have done something about it. Investigations, hearings, technical audits, best practices and standards. Statistical analysis to identify issues (as against the analyses that do happen that show insignificant fraud). He had 4 years to sort this out. You’d think it would be one if his top priorities.
Of course none of that happened because the whole show is entirely performative. In fact doing anything about it would take his excuse away, because if he addressed vote security he couldn’t blame vote security issues on anyone else.
