You claimed ballots provided the government with the information they needed to know who voted.
I pointed that is untrue. Ballots explicitly do not.
The fact you posted that tells you know have a Google level understanding of the law in the US, and the fact you posted an article about private citizens using public data as proof of the legality of government-operated mass surveillance data tells me you're a deeply unserious person who should probably read Robert's writing in the majority opinion in Carpenter.
