The Right to Bear Arms In Jeopardy

The National Rifle Association has a powerful new ad pointing out part of what is at stake in the future of the Supreme Court:

Keep in mind that for the last 7 years, the Supreme Court has been denying certiorari in numerous Second Amendment cases and failing to enforce its decisions in District of Columbia v. Heller (2008) and McDonald v. City of Chicago (2010). Those cases reclaimed the Second Amendment right to bear arms after a long period of desuetude and incorporated it against the states.
As the ad suggests, the addition of a single liberal justice to the Supreme Court will undo all of that progress.
