There is a simple solution, add an amendment to the long line of others that requires ALL voters to pass a test before they "earn" the right to vote. A simple 10 question test. It would drop the number of qualified voters to 25% of current. (I can HOPE for CHANGE!)
First question: "How many states are in the USA." That one alone would knock out Obombus and 50% of those who voted this year.
