The National Shooting Sports Foundation has just released a 30-second public service ad reminding people just what is at stake in this election. They remind people that one vote is what made the difference in the Heller and McDonald cases and that the next President of the United States will likely nominate at least one new Supreme Court Justice.
I think it is an effective and well done adverstisement. The NSSF has a special section on their website devoted to the #gunvote campaign. It has news, lets people find where their polling station is located, and has a registration guide for all 50 states plus the District of Columbus.
