If there really was fraud then Biden wouldn’t be about to take his seat in the White House. Trump has failed to provide any evidence for any wrongdoing hence the courts throwing his appeals out. Everything else is a crazy QAnon conspiracy theory.
The only video of alleged fraud I’ve seen (someone burning a pile of ballots) was quickly debunked because there were a number of details missing from the slips on the video that would have been on a normal ballot slip and therefore proven to be fake.
