Another of the Post-Civil War amendments, the Fifteenth was focused entirely on voting. Just to make things clear to everybody, it says that right for citizens to vote shall not be denied based on race, color, or whether or not they used to be a slave. And just in case anyone thought they weren’t serious, Congress said they had the power to enforce it. While good intentioned, we all know it wasn’t enough. Democrat States would go on to institute Pole Taxes and other ways of stopping the former slaves from voting that had absolutely nothing to do with their race, color, or previous slavery. It would be another century before enough Northern Democrats joined ranks with the Republicans to end those particular tactics.
