The proposition that in case of a supposed violation of the Constitution by Congress the States have a constitutional right to interfere and annul the law of Congress, is the proposition of the gentleman. I do not admit it. If the gentleman had intended no more than to assert the right of revolution for justifiable cause, he would have said only what all agree to. But I can not conceive that there can be a middle course, between submission to the laws when regularly pronounced constitutional, on the one hand, and open resistance (which is revolution or rebellion) on the other.
