In 1987 there was no federal voting standard, states were able to decide who has the ability to vote and who does not. So in this time period is when the U.S Constitution was adopted because there was not any type of agreement on a national standard for voting rights so this gave them the power to choose. Although some states had the rights to choose in most cases they would give the opportunity to white male landowners only. And because of this decision not until 1971, large numbers of American citizens were not able to vote. But the 14th, 15th, 19th, 24th and 26th Amendments were there for protection, protection of voting rights and that they cant be denied that right what so ever.
