Instead of making it easier to vote, maybe we should be making it harder. Why not test people about the basic functions of government? Immigrants have to pass a test to vote; why not all citizens?Answer: because the Voting Rights Act, recognizing that literacy tests have always been used for the purpose of discrimination against minority citizens, prohibits them.
(Just for perspective, here's a sample literacy test used in Alabama in 1965. Feel free to speculate about whether our friend the Cheeto taster would pass.)
