The problem is the same thing. The system isn't broke. The people are. The people are the problem, and the same people that broke the system would be the delegates.
The states will send delegates with specific powers, commissions. Florida has already provided for this.
The most common alternative suggestion from opponents to Article V is to enforce the existing constitution through the election of more conservatives.
Insistence that all we need to do is elect good men and women is no different from the Progressive belief that socialism will "work" once the best brains are put in charge. Both rely on a fantasy, that their conservative or progressive politicians are immune to nature. These dogmas are comfortable ruts which have been refuted throughout history, and reflect a naiveté and ignorance of American history, government and passions common to all men. Given the chance, men will grasp power and money, no matter the damage their avarice and ambition do to the larger society.
What has been forgotten or probably never understood by both progs and some Article V opponents, was accepted as an undeniable truth to the Framing generation; liberty is secured through the division of power. It clearly hasn’t been secured by nonexistent self-enforcing words in the constitution. In fact, just about all that remains in force from our constitution is the structure of the government. We still have the institutions of congress, courts and a president, but little more. Nearly every other clause has been excised or bastardized such that they’ve been inverted to allow infringement of our liberties.
Undivided power is despotic; it can be nothing else.
So, if the goal is restoration of liberty, and liberty requires division of authority, the question is how to return the states to the senate. Since our oppressors in DC will never divest themselves of power, and the framers provided a way to go around DC, it stands to pure logic that an Article V convention is our only hope.
