Native American voters face unique challenges to their right to vote. The LWV website details some of these challenges, e.g., geographic isolation, non-traditional mailing addresses, lack of residential mail delivery, etc. In 2020 the LWVUS filed an amicus brief to support the NAVRA. Urge your friends and political representatives to also lend their support for HR1694.
