John Birch Society also is very against the Convention of States, and lays out some pretty convincing arguments as well.
And even the most staunch pro-Convention writers can’t flat out say a “runaway” is impossible.
Near the core of John Birch Society opposition to an Article V Convention of the States is mistrust of the American people. Dig further and one cannot avoid the conclusion that JBS opposes the essence of republicanism, the right of all peoples to determine the structure and boundaries of their government. While JBS has no apparent problem with the exercise of the people’s electoral capacity at polling places every two years, they curiously stand athwart the exercise of the people’s sovereign capacity via their states to frame their government.
