More of the same. Suggesting that individual States do not now have the power and authority to oppose tyranny is false. Suggesting we need a law allowing three fifths of the states to oppose such tyranny is a law contrary to the Constitution itself and makes things more difficult for individual states to exercise their Sovereign power.
In other words, what we have here is a pot load of lazy or compliant States unwilling to put themselves in the Federal crosshairs, risking their Federal handouts, by doing what is right.
...and a COS trying to appear like they want the States to again exercise their God given rights of Sovereignty by suggesting law as a means of regaining the power usurped or plain given away.
I would certainly agree that a good start would be individual States NULLIFYING the seventeenth Amendment short of Congressional repeal.
