You may not know this, but your voter registration information and voting history is maintained by your state as a publicly available voting record.

Voter records normally contain the voter’s name, address, date of birth, citizenship status, identifying information like Social Security or driver’s license number (typically this information is fully or partially redacted in publicly released versions), place of birth (in certain states), party affiliation (in certain states), and a listing of the elections in which the voter participated (not who they voted for, just that they voted), and how they participated (did they vote in a primary, did they vote by mail, etc.).
