Interesting notion but if all the States could agree the Constitution would not prevent such an outcome.
Yeah it does.
"If all the states, save one, should assert the power to drive that one out of the Union, it is presumed the whole class of seceder politicians would at once deny the power, and denounce the act as the greatest outrage upon State rights. But suppose that precisely the same act, instead of being called "driving the one out," should be called "the seceding of the others from that one," it would exactly what the seceders claim to do; unless, indeed, they make the point, that the one, because it is a minority, may rightfully do, what the others because they are a majority may not rightfully do. These politicians are subtle, and profound, on the rights of minorities. They are not so partial to that power, which made the Constitution, and speaks from the preamble, calling itself "We the People."
