They used to have tests, poll taxes, and only allowed landowning white males to vote. All these laws served to do was to keep white men in power over women and minorities. The Supreme Court years ago ruled these practices unconstitutional. Our Constitution gives all of us the right to vote. If you believe in our Constitution and laws of the land, like you usually purport yourself to do, you would realize our government can't and shouldn't impose laws that discriminate against classes of people. Who was it that said that he may not agree with what you say, but will defend to the death your right to say it? Kind of the same situation here. I may not agree with the way an illiterate person may cast their vote, but I will defend their right to do so. That is the American way.
