You can't even wrap your mind around universal background checks by necessity requiring a universal registry so that you can actually ENFORCE universal background check laws.
You think ONLY one person is involved in ballot substitutions schemes. Your arguments are logically weak, weak, weak.
1. I've described for you a way to track guns without registering the owner. We currently have the requirement for background checks for purchases from an FFL...and yet no registration. How does that work?
2. I asked how did it happen...you cannot answer. How did thousands of ballots disappear from the printer, to find their way to the forgers? How did the forgers get names to forge...since that had to happen after all ballots had already been counted and the voter data base updated. Otherwise you'd run into a lot of duplicates.
Then...how did the forgers access to the precinct poll books to forge signatures? How did forgers change ballot counts to show absentee ballots had been brought in from drop boxes or the post office? How did the ballots get from the forgers to the election HQ and inserted to be counted? Remember, the count would have been over for hours by now....and someone is certainly going to notice a shit ton of new ballots arriving long after everyone has gone home.
