The correct answer is the end of legal segregation allowing U.S. citizens the right to vote.
The civil rights achievement of each administration that had the most far-reaching effect in the United States life was the end of legal segregation allowing U.S. citizens the right to vote.
The Civil Rights Act of 1964 and the Voting Rights Act of 1965 prohibited discrimination in jobs, education, and voting. The Civil Rights Act of 1964 is considered to be the best legislation on civil rights enacted by the United States Congress. It combated racial discrimination. The Voting Rights Act of 1965 allowed blacks to vote in the South, removing segregation requirements such as literacy tests, and poll taxes. That is why the civil rights achievement of each administration that had the most far-reaching effect in the United States life was the end of legal segregation allowing U.S. citizens the right to vote.
