A fine FReeper named Macbeth said back in 2000, "The Left may want a convention, but the Right owns the convention."
He called it. It is the means by which the states overrule Congress.
MacBeth said it almost perfectly because I think the Left would go into cardiac arrest if a convention were called. I think they know that it would be all over for them, game over.
We really do have the power but we have been constantly shuttered by fear of a convention spinning out of control when in fact that would never happen, never!
