It was always wrong.  But no one could explain exactly how votes were being corrupted in the 2020 presidential election.  Trump legal people like Rudy Giuliani and Sydney Powell ran around condemning voting machines and promoting shady allegations of fraud.  But they could never produce forensic evidence of wrongdoing - and both have suffered greatly for their advocacy.

Attorney General William Barr publicly stated that election fraud was committed. Then he disappeared.  To this day, President Trump is crazed over the vote. But he and his supporters were on the wrong trail.
