"I want to give you the reason why I believe that 18-year-olds should have the right to vote. Not because, as many say, if you are old enough to fight you are old enough to vote. That is one reason, but not the best reason. The reason that 18-year-olds should have the right to vote is that they are smart enough to vote. They know. They are interested and more involved than were the 21-year-olds of only 20 years ago. This is a tribute to your teachers. It is a tribute to your parents and it is a tribute to you. I wish that particular message to get home to this group as you complete this particular, very exciting experience that you have had."
