Charles C.W. Cooke has a pretty good article challenging the left’s “You paranoid sensationalist gun nuts always thinking people want to take your guns! Of course Hillary doesn’t want to repeal the Second Amendment.”
As anybody with an elementary understanding of American law comprehends, one does not need to call an Article V convention in order to effectively remove a provision from the Constitution. If, for example, Donald Trump were to claim tomorrow that the First Amendment did not protect an individual right to speech, how do we imagine that the press corps would react? Do we think that the New York Times’s editorial board would nonchalantly say “well, that’s fine because he hasn’t called for Article V repeal”?
Even without overturning Heller, her nominees would still have the opportunity to narrow to meaninglessness. Sure, outright bans might never come back, but de-facto bans, like the one that exists in New York City, could be upheld. Even Washington D.C. responded to Heller by enacting restrictions that were still quite onerous, and would never be considered acceptable in the context of other Constitutional rights. Chicago fared a little better, but only because the 7th Circuit was unusually cooperative, and it bolstered the negotiating position of the rest of Illinois, which favors gun rights. Without a fourth and strong pro-2A Supreme Court ruling, the Second Amendment is already dead letter.
