What does the 15th Amendment guarantee?

The 15th Amendment guarantees that voting rights cannot be denied based on race, which is a crucial aspect of ensuring that all citizens, regardless of their racial or ethnic background, have the right to participate in the electoral process. Ratified in 1870, the amendment was a significant step toward civil rights, particularly for African American men who had been systematically disenfranchised. The amendment aimed to eliminate race as a barrier to voting and laid the groundwork for future civil rights legislation aimed at enforcing and protecting the voting rights of all individuals.

While other options present important aspects of voting rights and electoral issues, they are not covered by the 15th Amendment. For instance, women's right to vote is protected by the 19th Amendment, representation for Washington D.C. voters is addressed by the 23rd Amendment, and the voting age was set by the 26th Amendment.
