This legislation directs the Comptroller General of the United States to undertake a comprehensive analysis of the Federal Government's performance in facilitating voting access for absent uniformed services voters under the Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA). The analysis will specifically examine data related to the transmission of ballots to and from these voters, including the efficacy and security of methods used, and the rates at which their ballots are counted or rejected by election officials, along with reasons for any rejections. It will also assess the effectiveness of assistance provided by Voting Assistance Officers and the coordination between these officers and State and local election officials. Additionally, the bill mandates a study focused on enhancing access to voter registration information and assistance for members of the Armed Forces and their family members. This study will evaluate potential actions for military departments to increase such access and estimate the associated costs and requirements to fully meet these needs. The Comptroller General is required to consult with military departments and utilize both existing information and independent investigations to complete this work, with a final report due to Congress by September 30, 2027.
