I agree with mister Lucky. In fact when texas entered the Union it had various clauses for breaking up WITHIN the Union but NONE for breaking OUT OF the Union.
TX could have broken up into 5 States, had she chosen to AND could have reasserted her rights as a FRee & independent republic, according to many scholars in 1861 or NOW for that matter.
150 years of DAMNyankee/elitist domination does NOT change the TRUTH that the Constitution (particularly the 9th & 10th Amendments thereto) does NOT outlaw UNILATERAL secession. secession is still an option for EVERY State or group of States. furthermore, the States created the union & remain FREE to change/secede from/abolish that union at ANY time that they so choose.
