You didn't answer the second part of my question.
How would you make that happen?
Literacy tests.
They are illegal, Jim.
Only because they were used for racial segregation and denying the vote to blacks.
If it were not for that they would be perfectly legal. And they ought to be.
How do you allow someone to vote who has no ideas of the issues, or even what the candidates stand for? The country was built on the idea of an informed electorate. This is why we had property qualifications. Take away the informed voter and you get pretty much what we have now.
