Without any further looking... I don’t want to change the Constitution - I want to preserve it! Big difference..
Not sure what you meant but will assume that you also meant preserve the Constitution until I know otherwise.
This is a way of preserving by erecting a fence of contemporary language that cannot be avoided or subverted. The Bill of Federalsim turns the clock back to the orginal intent of the framers.
I think convening a convention is the only responsible way to preserve the constitution. Too many loopholes have been found in the last 200 years and they need to be closed. By us.
