The PROVE Act would require all states to allow 16-year-olds to pre-register to vote for federal elections, with their registration automatically activated once they turn 18. States would have 90 days from the bill's enactment to establish this pre-registration process, and they could optionally extend it to even younger voters. Additionally, the bill directs the Election Assistance Commission to award grants to states for programs that increase youth participation in elections, including promoting the pre-registration process and updating school civics curricula. The legislation authorizes $25 million in federal funding for these state grants, which would be distributed over two-year periods with states required to report back on their progress and results. The bill aims to boost voter engagement by making registration easier for young people and integrating civic participation into secondary education.
