revise provisions associated with residency for voting purposes.

Redefined 'residence' to require an actual fixed permanent dwelling with 30 consecutive days, emphasizing physical habitation over mere mailing addresses.

Updated voter registration requirements to explicitly require individuals to be actual residents of South Dakota rather than just maintaining a mailing address.

Created a new 'national voter' category for individuals who register using only commercial mail receiving agencies or PO boxes without providing a physical habitation address.

Added restrictions that national voters can only vote for federal offices (president, senators, representatives) rather than state or local positions.

Required county auditors to mark national voter ballots separately and prepare ballots listing only federal candidates for these voters.

Modified ballot challenge procedures to include residency verification as a ground for challenging a voter's eligibility.
