I’m not talking about voter registration per se, which should be greatly tightened up however.
I’m talking about registering an online voter account if you are already a registered voter. This part must be stringent because afterwards you have no interaction except online. No showing your ID to vote at a poll, no signing a mail-in ballot and having your signature checked. The only chance to control access is at the moment of setting up the account. It must be stringent, or the deal is off.
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.
