For example, when he assured New Yorkers that the powers of the national government would be “few and defined.” He was totally wrong.
The fact the 'we the sheeple' allow the federal government to run rough-shod over our Constitution does not mean Mr. Madison was 'dead wrong'.
In my studies of Mr. Madison I have found him to be quite perceptive in his analysis/predictions of the abuses which could/would be perpetrated against our Constitution by unenlightened 'statesmen'.
