The main purpose of the State and Local Election Security Act of 2026 is to provide funding for election security grants over the next three fiscal years (2026, 2027, and 2028). The act aims to enhance the safety and security of elections in the United States by ensuring that state and local election officials have the necessary resources to improve election infrastructure and respond to potential security threats. Key provisions of the act include the establishment of an election security grant program that allocates funds to states based on their voting age population.
