Well if you watch the hearings that were held in PA, GA, and AZ after 2020, that's a good start. The Navarro report looks exhaustive although I've only read the summary. Seth Keshel outlines many anomalies. Sure, the exit polling in 2020 did generally line up with the final result, but do you remember how far off exit polling was in 2016? It had Trump losing Ohio (he won by 8%) and losing Florida by 9% (he won by 1%), etc.

But your point is well taken and I make it all the time. Trump likes to brag about how most of law enforcement is secretly on his side, but where were they in 2020 (and 2018 and 2022 for that matter)?
