A critique of the Media matters GRPC hit piece by someone who was there.

Media Matters GRPC report ignores anti-gun background check deception

This much Media Matters got right: Gottlieb believes background check bills are inevitable. He supports his position with polling data and information he has managed to obtain that bolster his assessment. He therefore advocates that it’s in the interests of gun rights advocates to steer and shape legislation to mitigate damage and obtain concessions, and even roll-backs. For his part, Knox refuses to cede an inch. He advocates dealing with the political and other consequences of laws he knows will prove to be failures.
