This election season, voters could do worse than remind themselves of the warning in James Madison's "Memorial and Remonstrance":
"... take alarm at the first experiment on our liberties. We hold this prudent jealousy to be the first duty of Citizens, and one of the noblest characteristics of the late Revolution. The free men of America did not wait till usurped power had strengthened itself by exercise, and entangled the question in precedents. They saw all the consequences in the principle, and they avoided the consequences by denying the principle. We revere this lesson too much soon to forget it."
Yes, be alive to the underlying assumptions of the two presidential candidates and to the consequences of their principles.
