Better Petitions. Healthier Democracy.
Before an initiative is put on the ballot, the signatures must be go through a verification process, where the Secretary of State checks that the person who signed is a registered voter, and actually signed the petition themselves. When petitions have illegible signatures, it's difficult to verify them.
The Secretary of State (or your designated state official) or the state courts generally do not want to approve unverified signatures, but also do not want to discredit actual signatures, so the petitions usually get passed without thorough verification. We're working to solve this.
