Suppose you do so and in a speech you say that maybe in 75 to 100 years in the future we will have many more states. Some of the states will want to leave the Union. The others won't want to let them. A horrible civil war will start where hundreds of thousands of men will die. So you think we should put in the Constitution that either states should or should not have the right to secede because if neither way was explicitly stated each side would claim the constitution would back them up, whereas if the constitution did take a position many people would hesitate to violate it and much if not all the bloodshed could be avoided. Do you think you could sell the delegates on that? Any chance if you found yourself a delegate you wouldn't even try?
