As they say in North Dallas Forty, seeing through the game is not the same as winning the game. If there was one, I think The Steal in 2020 was thousands of little nods and winks and rule-bendings by Democrat election officials, not some grand conspiracy.
Trump and the GOP did much better this time, setting up a TEAM that was prepared for all chicanery. He'll finish with about the same number of votes as 2020, and Kamala will have got 10 million less than Biden. So yes, Biden might have got millions of fake or invalid votes, and better preparation by the GOP scared the Dems off from repeating The Steal. But we will never know.
I never bought The Steal. In the least Trump neither headed it off or proved it. Like when he said McCain wasn't a hero just for getting his plane shot down and getting captured, anyone who gets cheated is still a loser. Politics is a dirty game and he was too lazy and vain to prevent it.
But not this time.
