Which amendment allows anyone regardless of race to vote?

The 15th Amendment to the United States Constitution specifically addresses the issue of voting rights in relation to race. Ratified in 1870, it states that the right to vote cannot be denied or abridged by the United States or by any state on account of race, color, or previous condition of servitude. This was a significant step in the ongoing struggle for civil rights, especially for African American men who had been systematically denied the right to participate in the electoral process prior to its ratification.

The other amendments mentioned relate to different aspects of voting rights. The 19th Amendment, for instance, grants women the right to vote but does not address race. The 24th Amendment prohibits poll taxes in federal elections, which were used to disenfranchise poorer voters but again does not specifically mention race. Lastly, the 26th Amendment lowers the voting age to 18, ensuring younger individuals can vote but also does not pertain to race. Hence, the 15th Amendment is the correct choice as it directly ensures that voting rights cannot be denied based on race.
