I favor a minimal intelligence test for all voters.
We had a situation in my home county where there were 6 candidates for U.S. President.
The result was a bunch of "spoiled" ballots where there were so many candidates, voters thought they could do multiple choice and vote for more than one.
Nice.
I could get behind that.
I imagine the Founders might have made it a pre-requisite for voting if they could have foreseen the pathetic state of the current electorate.
