"The second feature I dislike, and greatly dislike, is the abandonment in every instance of the necessity of rotation in office, and most particularly in the case of the President. Experience concurs with reason in concluding that the first magistrate will always be re-elected if the constitution permits it. He is then an officer for life. This once observed it becomes of so much consequence to certain nations to have a friend or a foe at the head of our affairs that they will interfere with money and with arms. A Galloman or an Angloman will be supported by the nation he befriends. If once elected, and at a second or third election outvoted by one or two votes, he will pretend false votes, foul play, hold possession of the reins of government, be supported by the states voting for him, especially if they are the central ones lying in a compact body themselves and separating their opponents: and they will be aided by one nation of Europe, while the majority are aided by another. The election of a President of America some years hence will be much more interesting to certain nations of Europe than ever the election of a king of Poland was. Reflect on all the instances in history antient and modern, of elective monarchies, and say if they do not give foundation for my fears, the Roman emperors, the popes, while they were of any importance, the German emperors till they became hereditary in practice, the kings of Poland, the Deys of the Ottoman dependancies. It may be said that if elections are to be attended with these disorders, the seldomer they are renewed the better. But experience shews that the only way to prevent disorder is to render them uninteresting by frequent changes. An incapacity to be elected a second time would have been the only effectual preventative. The power of removing him every fourth year by the vote of the people is a power which will not be exercised. The king of Poland is removeable every day by the Diet, yet he is never removed."
