I saw some chatter in the comments section about the NRA. Today's awful Washington Post editorial also mentions the organization.
While I have no doubt that the organization will mention yesterday's decision in its fundraising letters, it's worth noting that the NRA fought yesterday's winning lawsuit every step of the way. They refused to support the suit at its outset, then, for whatever reason (I'm going with any number of public choice explanations), filed a series of motions to kill it (or at least dilute it), likely because the group would then have to explain to its members why it wasn't party to what may be an historic Second Amendment victory.
Just to be clear, this was a victory for gun rights, not a victory for the NRA.
