I'm betting it has a lot to do with public perception. There will (or should) come a point where the truth of how they stole the election will be undeniable. This audit, if done properly and fully documented, will make it undeniable. It's going to get out among conservative circles and eventually the normies are going to catch wind of it and wonder why the news isn't reporting on it. So the MSM will have to report on it. Then they'll have to report on how the machine recounts were legitimate but the full forensic audit isn't. It really creates a problem for the narrative. We should see a lot of people waking up then... Hopefully.
