"NRA receives 350M/yr in 2014"
"NRA has received, in total, 80M from individual donors in the past 13 years"
"NRA received 22M from individual donors in 2014"
22M of 350M revenue means that individual donors are very small.
Where does the other 330M per year come from, if not individual donors?
The NRA (I’m a member, and my wife) has at > 4M members. It’s $30/year, so that is $120M/year just in membership fees. You are only counting donations, which are separate.
Suggest you read John Lott to see how the media and manipulates gun statistics.
