We will never have the informed electorate we all yearn for. It just isn't possible without curtailing way too many individual's right to vote. Besides, how would we fairly determined what "informed" fairly means? A certain minimum IQ or svhool grade level accomlpished? A reading test? How about a civics test?
We started out only allowing white, male landowners to vote. For sound reasons, this has been expanded to include non-whites, non-land owners and woman. How can one certain we should go backwards in our self-defined "democratic" society?
