James Buchanan's Message to Congress Is About as Confusing as It Could Be

James buchanan is going to send in his a message to congress. Not go and deliver a state of the union like we think of to day. That's not in the constitution. He on the one hand as that no state can legally leave the union. Is not allowed under the constitution. But at the same time he's saying that the federal government has no power to stop anyone from leaving the union, right? So it's illegal under the constitution, but i don't know how to folks to stay.That's a sort of the constitutional argument here.
