When the AG of that place concedes this, it means something(emphasis mine):
[T]he State agrees with defendant’s reading of United States Supreme Court precedent. To briefly recap Second-Amendment jurisprudence, the
United States Supreme Court held that “the Second Amendment extends,
prima facie, TO ALL INSTRUMENTS THAT CONSTITUTE BEARABLE ARMS, EVEN
THOSE THAT WERE NOT IN EXISTENCE AT THE TIME OF THE FOUNDING,” District
of Columbia v. Heller, 554 U.S. 570, 582 (2008), and that this “Second
Amendment right is fully applicable to the States[.]” McDonald v.
Chicago, 561 U.S. 742, 750 (2010).”
Right there is a big reason Clinton lost: her attitude toward Heller was "We need to get rid of it, because Common Sense Regulation." And I guarantee that caused some people to vote for Trump.
