Why does Frederick Douglass claim that without the right to vote, the black man’s “liberty is a mockery?

Explanation:

Frederick Douglass claims this because, in the eyes of the American people, the right to vote is a part of liberty. Those with the right to vote are free to make their own choices, and for those choices to be heard. Even though black people were freed from slavery, they still didn't truly have a voice without the ability to vote, so their influence in important areas such as the government was next to none. Therefore, though they were no longer slaves, they hardly had liberty.
