Honestly, I would find the statement that "The 2020 elections had serious problems and here's the evidence for what and why..." to be almost trivially easy to follow up in an honest, forthright, and voluminous manner. Republicans did a lot of deeply problematic crap as long-term groundwork for elections in general beforehand and an extraordinary amount of deeply problematic crap directly involving that specific election.
Pretending that Trump even could stay on script to make a case of that nature in the first place in the imaginary circumstance that there was valid evidence for his oft repeated lies, though, is a deeply unreasonable pretense.
