The Heritage Foundation’s Daily Signal reported on Tuesday that conservative scholar Charles Kesler warned of a “crisis of the two Constitutions”—liberal and conservative—and said that failure to win through persuasion or to reinvigorate federalism could lead to secession or war.

He described one Constitution, the original 1787 document as amended, as steeped in natural rights and limited government. This one, he said, is also the “conservatives’ Constitution.” The other one is the “living Constitution,” or what he called “the liberals’ Constitution.” “The living Constitution implies that the other Constitution is a dead Constitution, or at least is on life support, and that it must be transformed, it must be infused with new meaning, new ends and to some degree new means and institutions, to be kept alive in order to be a vital part of our politics,” Kesler said.

Kesler said that a “cold civil war” broke out when conservatives fought back:
