Where do you get that from? There is nothing in the Constitution which prevents a state from being expelled, so your talk about secession and new republic is ridiculous. We aren't forming a new republic, we're expelling Massachusetts from our existing one. So we just do it. Tell Massachusetts that they are no longer a state, redo the flag, put customs posts around the border, cut off social security payments, etc., and it's done. Hell, we wouldn't need 49 states, just a majority vote in Congress to pass the legislation cutting off Massachusetts from the rest of us. Why isn't it as easy as that?
Article V - [N]o State, without its Consent, shall be deprived of its equal Suffrage in the Senate.
Once again you've turned our republic on it's head. The Constitution acts as chains on the power of fedgov; the 10th Amendment thereto insures that it shall never be reversed. Expulsion of a state by federal action would be an unenumerated power and thus the only way it can exist would be if it were necessary and proper to carry out one of the enumerated powers. It is not.
This is the same bass-ackward interpretation of our system of government that you've used a hundred times in justifying suspension of habeus corpus. Expulsion of a state is an unenumerated power. Suspension of the writ is specifically delegated to the legislature. "It's not in there" is the admission that you make. What does the BOR say about powers that are "not in there?" How is it the most basic elements of Republican government escape you?
