One of the "hotshots" Trump trotted out after 2020 to prove fraud was some guy named Seth Keshel former military intelligence who claimed using statistics he could prove Biden didn't actually win and the vote totals were so above forecast turnout they had to be false. He then went on a paid speaking spree doing hundreds of events where he explained how Biden didn't really win. Trump and Bannon love the guy.
He's now claiming that the Census was intentionally hosed in 2020 and as a result 16 electoral votes that should have gone to Trump, went to Harris, and other seats too. Trump is already sharing it as is Musk.
Note, some clever Dem who had apparently gotten fed up took the formula Keshel presented over and over after 2020, and applied it to 2024 and hey guess what, it says the 2024 election was fraudulent too, Kamala Harris got far lower vote totals than she was forecast to get so clearly it was fraud. Note he's not actually claiming fraud just pointing out Keshel is a phony.
