The (Article V) Convention Lobby’s whole case rests on their false claim that George Mason said that when the federal government violates the Constitution, the solution is to call a Convention to amend the Constitution.
But Mason never said such a silly thing. Nor did any other Delegate to the Federal “Amendments” Convention of 1787.
Please also note James Madison’s warnings at endnote 3 that those who secretly wish for a new Constitution would push for an Art. V Convention under the pretext of getting Amendments.
That’s what’s going on today.
