"There are times that I want to have tests given to ensure that a prospective voter at least has a concept of rational thought."

Something similar was tried in the South and shot down by the Supreme Court. One of the schemes for keeping blacks out of the voting booth was to give prospective voters a test on reading and understanding the state constitution, which, as I recall, was said to be pretty challenging reading. Presumably this was combined with less money going to schools that had more than average numbers of black students.
