This document discusses the history and evolution of voting rights in the United States. It outlines how the Constitution established states' rights to set voting qualifications but also placed restrictions. Over time, amendments expanded voting rights by removing barriers such as race (15th), sex (19th), poll taxes (24th), and setting the minimum age to vote at 18 (26th). The document also reviews current voter qualifications set by states such as citizenship, residency requirements, registration, and exclusions of certain groups like felons.
