Third-party voter registration

From Ballotpedia

Third-party voter registration is when Person X solicits or encourages Person Y to register to vote in a given state, when Person X is not a government employee or election official but is, instead, working on behalf of a group that is conducting a voter registration drive. Third-party voter registration drives are similar to petition drives, except that in a petition drive, a circulator is asking a voter to sign a petition to qualify an initiative for the ballot, and in a third-party voter registration drive, the solicitor is asking a person to sign up to become a registered voter.
