Will registering for an online account in person stop corrupt officials from creating fake or fraudulent registrations? No and the way you will know it happened is the purchase of 100,000 burner phones in Philly. Will any court in the country allow a state to require in person registration at a trustworthy location e.g. a location where both parties can observe and verify every registration? Unlikely, and if they did the corrupt dem jurisdictions would kick out the republican observers just like election night.
