“The original Constitution doesn’t have much to say about the right to vote. Indeed, nowhere in the text does it explicitly say that citizens have the right to vote in elections. Instead, it merely states that anyone eligible to vote for the largest house of a state’s legislature is also eligible to vote for members of the House of Representatives from that state. As a result, states were left with the power to decide who qualified to vote, leading to considerable variation in the nation’s early years. While most states initially restricted voting to property-owning or tax-paying white men, some states, like New Jersey, allowed free Black men and women of both races to vote provided they met the property or tax requirements. While states soon began expanding voting rights to more citizens, this process unfolded unevenly because it was left up to each state. New Jersey actually revoked the vote from Black men and women in 1807 and North Carolina didn’t remove a property qualification until 1856. Similarly, Wyoming granted women the right to vote in 1869, long before all women achieved it nationally. This variability continues today, which is why felons can vote in some states but not in others.”
So some states let you vote from prison, some don’t. Some restore the right on release, some don’t.
