Constitutional amendments, on the other hand, should be more sharply limited. Their ratification should require the approval of 2/3 of the voters - not only 2/3 of those who vote yes or no, but 2/3 of all those who show up to vote that day at all, for anything. Hence, no vote would count the same as a "no" vote.
I spent an extraordinary amount of time educating several elderly Florida voters about each of them in 2002. For goodness sakes, one of the amendments was 2/3 page long in small print. It was fraught with legalese babble, including about 6 sets of double negatives.
