What is your interpretation of the Fifteenth Amendment?

"The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any state on account of race, color, or previous condition of servitude."

all citizens may be able to vote regardless of colour or social status and the government does not have the authority to change this (shall not be denied or abridged by the United States), but this does not include women as they do not strictly mention gender. Previous condition of servitude likely refers to how slavery was abolished and that former slaves shall also have the voting right.

Explanation:

"The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any state on account of race, color, or previous condition of servitude."
