In other words, 5.2 million NRA members represent only 6% of the 79 million gun owners in America and are carrying the majority of the load protecting the 2A for the rest (With the help of those members of GOA, SAF, Jews for the Preservation of Firearms Ownership, and the various state R&P associations, of course). NRA is not perfect, but it is the oldest, largest and most feared by politicians who would destroy the 2A if they could.
Brings to mind Paul Harvey's old saw, "It takes more to pull the wagon than can ride on it.", doesn't it?
