Which amendment provides the right to vote for all races?

The 15th amendment is pivotal in U.S. history as it specifically addresses voting rights. Ratified in 1870, this amendment prohibits the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude." This was a significant step in the Reconstruction Era, aiming to ensure that African American men, in particular, had the legal right to participate in elections after the Civil War.

The 14th amendment, while it guarantees equal protection under the law and defines citizenship, does not explicitly grant the right to vote. Instead, it addresses citizenship and the rights of citizens. The 19th amendment focuses on women's suffrage, granting women the right to vote, and the 26th amendment lowers the voting age to 18 years, ensuring that younger citizens can participate in elections. Each of these amendments plays a critical role in the expansion of voting rights, but the 15th amendment specifically affirms the right to vote irrespective of race, making it the most pertinent choice in this context.
