Reducing Barriers for Military Voters Act This bill requires the Department of Defense (DOD) to develop a plan for providing end-to-end electronic voting services (e.g., services for registering to vote and returning a ballot) in participating states for absent uniformed service members who are deployed or mobilized in locations with limited or no postal service. Specifically, DOD must develop the plan by consulting with state and local election officials. Further, the plan must include (1) methods to ensure that voters have the opportunity to verify that their ballots are received and tabulated, (2) methods to generate a verifiable and auditable vote trail, and (3) an assessment of whether commercially available technologies may be used to carry out the plan. DOD must implement the plan for a trial group of voters in participating states for the 2024 federal elections. The plan must be implemented for all voters in participating states for the 2026 federal elections and subsequent years.
