I remember a con-con was being pushed about 15 years ago, but they backed off for some reason.
Perhaps they hadn't bought off enough legislators yet, or perhaps they were afraid of the response from Patriots, or perhaps there were enough Patriots still at high enough levels to kill the idea.
There mere suggestion of a con-con by the elites demonstrates their contempt for the Constitution.
They have attempted to subvert the Constitution through legislation. They have attempted to redefine it through the courts. They have tried to make it irrelevant by ignoring it. Only a fool would not expect them to destroy through the means of writing a new one.
I would expect that the new Constitution would be drawn from some combination of the old Soviet and German constitutions, with enough American 'catch phrases' from our existing Constitution to fool the sheeple into thinking there isn't much difference.
A new constitution will probably have a "bill of rights", but in the following form: "the people will have the right to (fill in the blank) unless the gov't says otherwise".
AKA the UN's "Universal Declaration of Human Rights".
