I actually think a constitutional convention would be a good idea. The constitution does not spell out how delegates would be chosen but presumably it would be up to each state which means delegates could be appointed by the legislature or selected by a state convention or even elected. My guess is that most state legislatures are most concerned about both the erosion of the 10th amendment and the incredibly broad latitude the courts have allowed the Feds under the commerce clause and I believe at the state level these concerns cross party lines. If I am correct about that then the states could appoint delegates and send them with specific language in hand.
As the Feds would never limit their own power the only salvation for the rest of us is if the states will assert their own rights and if they don’t this cold be the beginning of the end of the Republic. The congress will not listen to the people. The federal courts will not restrain the executive or the legislature and the states seem powerless to assert their prerogatives.
The 1992 law states that the states must hold special elections for the position of convention delegate. The model is similar to the Electoral College, where each congressional district would elect one delegate, and each state would elect two delegates at large.
But there are democrates who could easily be appointed as delegates depending on each state and how they view this....and we know how they play...Stupak comes to mind.
