The significance of the Voting Rights Act in U.S. politics lies in its role in protecting and expanding suffrage for marginalized populations. Enacted in 1965, it aimed to eliminate racial discrimination in voting practices, addressing barriers such as literacy tests and poll taxes that historically disenfranchised African Americans. The Act's provisions empowered federal oversight of voter registration and election procedures in areas with discriminatory practices. Its legacy includes increased voter participation and heightened awareness of electoral rights. However, ongoing challenges and proposed changes to voting laws underscore the continuing struggle for equitable access to the franchise.
