Absentee voting; revise various provisions of.

This Mississippi bill updates the rules for absentee voting to streamline the process for in-person voters and expand access for specific groups. It requires that application forms and witness certificates be printed directly on the ballot envelope for those who vote in person at the registrar's office, while also allowing on-call workers and people incarcerated for non-disenfranchising crimes to request absentee ballots. The legislation further clarifies that a signature mismatch will not lead to a ballot being rejected if it was cast in person, and it mandates that mail-in ballots must be returned only by mail or common carrier. Additionally, the bill updates the text of several existing state codes to ensure they align with these new procedures and requirements.
