Amends TCA Title 2 and Title 55, Chapter 50.

Tennessee HB0458 mandates monthly comparisons of the statewide voter registration database with the department of safety database to ensure non-U.S. citizens are not registered to vote, while also expanding the databases for such comparisons. It affects registered voters and county election commissions by establishing a process for challenging voter qualifications, increasing absentee voting age from 60 to 65, and requiring optical scanners to produce digital images of ballots. Key provisions include more frequent address verification, mandatory checks for residency and citizenship before voter registration, and specific identification requirements for non-citizen residents.
