What is?
Voting records are public records.
We have listings by street address as well as the actual registration book where people sign in.
I beleive your birthday, certainly your Soc Sec number, things like that are private.
But name and address and party registered are public.
This is how you end up on mailing lists from the DNC, RNC and any others with money and resources.
How you voted is secret. The fact you voted is not.
If you show up to vote again, everyone can call you out on it, not just the friendly people behind the desk that you slipped a token of appreciation too.
