What makes you think such an amendment would pass? The same ones who elected these people would vote against it.
Neither the people nor their reps will sit in convention. States will send delegates with commissions. There is a building groundswell of opposition, and state legislators know very well that DC is strangling the states. States have interests distinct from the people at large. Recall that a majority of states challenged Obamacare in court. When a convention is held, the media will not be able to ignore it. I expect a great constitutional reeducation will take place across America. The outcome isn't certain, but the Framers gave us a peaceful way to correct our mistakes and restore freedom.
