Unlike the questions which we have hitherto treated, this is not a question of constitutional legislation, but of what may more properly be called constitutional morality--the ethics of representative government. It does not so much concern institutions as the temper of mind which the electors ought to bring to the discharge of their functions, the ideas which should prevail as to the moral duties of an elector; for, let the system of representation be what it may, it will be converted into one of mere delegation if the electors so choose. As long as they are free not to vote, and free to vote as they like, they can not be prevented from making their vote depend on any condition they think fit to annex to it. By refusing to elect any one who will not pledge himself to all their opinions, and even, if they please, to consult with them before voting on any important subject not foreseen, they can reduce their representative to their mere mouthpiece, or compel him in honor, when no longer willing to act in that capacity, to resign his seat. And since they have the power of doing this, the theory of the Constitution ought to suppose that they will wish to do it, since the very principle of constitutional government requires it to be assumed that political power will be abused to promote the particular purposes of the holder; not because it always is so, but because such is the natural tendency of things, to guard against which is the especial use of free institutions. However wrong, therefore, or however foolish, we may think it in the electors to convert their representative into a delegate, that stretch of the electoral privilege being a natural and not improbable one, the same precautions ought to be taken as if it were certain. We may hope that the electors will not act on this notion of the use of the suffrage; but a representative government needs to be so framed that even if they do, they shall not be able to effect what ought not to be in the power of any body of persons--class legislation for their own benefit.
