Felon Disenfranchisement

[BmorePat87]

Poll taxes and tests that were designed to shut down black voters also effected poor white voters, but the people in power still implemented them because in the long run it meant more success in elections.

If you're disenfranchising equal numbers of white and black people, you're going to win elections. The white people offset in terms of party affiliation while the black people more drastically impact the electoral success of your opponents.
