If you think the retraction of voting rights is due to the actions of men some 300 years ago, I dont really have much to say... You might as well go back a few thousand years. However, if you're interested in the actual cause and effects of real, tangible actions and real legislation by living souls. People whose goals were to repress votes to change outcomes, I suggest you study the last 30 years of American media and how the Right morphed the rules to their benefit.
