Election Laws - As introduced, prohibits online voting, except for the electronic provision of voting materials to military members and citizens abroad; prohibits the use of a post office box for establishing residency for voting purposes; requires a registered voter who moves to a different county in this state to vote based on current residence regardless of whether the voter has updated the voter's registration. - Amends TCA Title 2.

SB 645, a Tennessee legislative bill that was withdrawn on March 25, 2025, would have made three key changes to voting rules. It would have banned online voting for most voters (except military and overseas citizens who already have specific provisions), prohibited using post office boxes for voter registration or voting addresses, and required voters who moved counties within Tennessee to vote based on their current residence without needing to update registration. The bill directly affected all Tennessee voters by altering how they register, establish residency, and cast ballots. It amended Tennessee Code Annotated Title 2, specifically sections on voting equipment, address requirements, and residency voting rules.
