NRA, "Chipping Away at Our Second Amendment Rights"

What it says: “Mountains of debt, threats to our sovereignty, chipping away at your rights, chipping away at your freedom. And now, they’re attacking our Second Amendment rights, but you can stop them right now. Defend freedom, defeat Obama.”

Who will see it: It's a $1.3 million buy in Ohio, Virginia, Florida and Wisconsin. That's not a huge buy, but the group plans to be on the air through Election Day.

What it means: President Obama has not pushed any gun control legislation while in office, but he has long been opposed by the National Rifle Association and viewed suspiciously by gun-rights advocates. The group's decision to get involved in the race will be a test of its political clout.
