How did the voting rights acts of 1869, 1920, and 1971 expand the "blessings of liberty" to more of the united states population?

It allowed minorities and women to vote which made more people want to travel to america

from my own personal expirence food stamps has alot this makes it eaiser so we can affod bills and so we can life a better lifestyle not needing to worry about paying actual money to buy food since most people spend 100-300 dollars a month on food so this alot so we can afford other bills and other stuff we need
