The right to secede

A President violating the Constitution does not create Constitutional precedent. The Constitution has enumerated powers. It then leaves all other powers not denied to the States and the People. It provides an Amendment method for adding powers. Therefore, the States have a Constitutional right to secede because the Constitution does not deny it to them...... Do I need to go through US history and point out all the places where men in power have been wrong? Where they have been blinded to logic and reason by what their IDEOLOGY, by what they WANT to believe?
