No, the answer is to build a super-majority in favor of a return to constitutionality. Without this, a con-con can only create problems, not solve existing ones.
Of course, if there is a super-majority of Americans in favor of a return to constitutionalism, these problems wouldn't exist, would they?
If we cannot win simple majority elections, what in the world makes us think we can pass an amendment, which is at least 10x more difficult?
IOW, we have met the enemy and they is us. The American people must change to solve this problem. And that occurs in the culture, which conservatives have almost entirely abandoned attempts to influence.
Root cause of problem stated right there.
Or, to quote Adams "Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other."
It is possible that since a growing majority of Americans are no longer moral OR religious (hence the cultural rot), our Constitution is inadequate to restrain wickedness of a people who are no longer governed by biblical morality.
A people who are not governed by God will be ruled by the tyrants of men.
Here we are.
