If it aint broke, dont fix it!
The problems we are experiencing today are not a result from flaws in the Constitution itself, but the lack of adherece to the Constitution.
There is an exceptionally dangerous potential that if the Constitution itself can be completely altered, it will be altered to promote Big Government instead of the original intention of a Limited Government. Might as well just "throw it in the woods" and have corporations write our Neo Constitution, that benefits them, and only them. Legalized Facism.
There are very few people that would partake in the Constitutional Convention (Con Con) that have any desire to represent the best interest of the People, not the Corporations or Big Govt.
If the Con Con starts, its all over. The United States as we all knew her will truly be dead, forever.
