That's the problem with most conspiracies: They just take so many people "being part of it" that a non-delusional person would conclude it was impossible to keep it secret. True believers seem to think all those perpetrators are so dedicated there isn't one who is a human being: That is has doubts, feels guilty, talks to their spouse or friend, gets drunk and brags about it, etc. In the real world, any secret known by more than one person gets out. This is basic human nature. Telling somebody "secrets" is how we bond with them.
The election fraud conspiracy would take thousands (10s of thousands?) of conspirators, all acting in concert, all keeping many secrets. Believing it requires denial of reality to the point of psychosis. I'm afraid we are going to end up with millions of people who need psychiatric intervention.
