A lot of articles out there on the NRA and ALEC lately.
But not many articles detailing the length of the relationship between the NRA and ALEC – so I though I would help them out a bit.

BY CHRIS W. COX, NRA Institute for Legislative Action
In a few short weeks, the Supreme Court will deliver a decision that will have a great impact on all Americans’ Second Amendment rights. If the Court’s decision is favorable, American gun owners will be on the verge of a major step forward—due in large part to the support of organizations like the American Legislative Exchange Council (ALEC) and its members.
Chris W. Cox is the executive director of the NRA Institute for Legislative Action. The NRA is a member of ALEC’s Public Safety and Elections Task Force.
Over 20 years - that would definitely be a long time.
