I agree on both points.
Imagine the liberals jumping at the opportunity to write a new constitution.
In 2014, America is a police state. The institutions that brought us to it, can hardly be expected to suddenly reverse course. Obama has established precedents such that national elections increasingly serve to confirm who will be our next tyrant.
Patriots have been backed into a corner, and there is but one remaining, possible way to restoration of republican freedom.
Article V.
And by this I assume that you think that an Article V Convention (aka Convention of the States) would provide liberals this opportunity.
You have no basis in fact for this assumption. First, any Convention of the States must be convened for a stated purpose - and to propose, not adopt - amendments to further that purpose.
Every state represented at the Convention - and they don't all need to attend, but we can assume that they will if one is called - have exactly one vote. Liberal states will be outnumbered by relatively conservative states.
All amendments proposed by the convention will have to be ratified by at least 3/4 of the states. Do you really think that the kind of Constitutional hijacking you seem to fear would meet the approval of 3/4 of the State Legislatures?
There is a good chance that an Article V Convention would end in failure to get agreement on the amendments to propose, or that the amendments proposed would fail to secure ratification, but there is no practical reality where we would wind up with a liberal wet-dream new Constitution.
The way we get that is to continue on our current course of piecemeal gutting at the hands of a self aggrandizing federal bureaucracy and out of control federal court system.
