Another name for secret ballot
https://en.wikipedia.org/wiki/Secret_ballot#United_States
In the United States the practice became known as the “Australian ballot”, defined as having four parts:
an official ballot being printed at public expense,
on which the names of the nominated candidates of all parties and all proposals appear,
being distributed only at the polling place and
being marked in secret.
