The ad features Kristi McMains, a lawyer from Indianapolis, whose would-be assaulter brought a knife to a gun fight.
"A man attacked me in a parking garage, tried to stab me with an eight inch knife," McMains, 26, recounts. "But I carry a pistol. I fight back. That's why I'm still here."
"Every woman has a right to defend herself with a gun if she chooses," she continues. "Hillary Clinton disagrees with that."
The ad is a tired, baseless refrain that the NRA and Trump campaign push. The Democratic presidential nominee did not want to "abolish the Second Amendment," as her Republican opponent has alleged. She has, however, challenged the gun lobby and pushed for universal background checks. A year ago, at a primary campaign stop in Manchester, New Hampshire, Clinton suggested more reasonable NRA members "form a different organization and take back the Second Amendment from the extremists."
"Donald Trump supports my right to own a gun," McMains continues.
NRA spokeswoman Jennifer Baker told Politico that, as of Wednesday, "The ads are running on broadcast networks in Ohio, Nevada, North Carolina, Pennsylvania and Virginia, as well as national cable" in an effort to reach female millennial voters in battleground states.
