Politifact
In March 2013, Lee Leffingwell, then the mayor of Austin, Texas, made
a two-part claim that includes the claim Taylor made. He said 90
percent of Americans and 74 percent of NRA members support background
checks of gun purchasers. PolitiFact Texas rated his claim True.
The key evidence was an article published
in the New England Journal of Medicine on a poll done in January 2013
by two entities at Johns Hopkins University -- the Department of Health
Policy and Management and the Center for Gun Policy and Research.
The poll was conducted online among 2,703 adults -- including 169 NRA members -- through GfK Knowledge Networks,
which specializes in working with academic and government researchers
to do polling online. It recruits participants randomly via mail and
telephone.
The poll found that 74 percent (to be precise, 73.7 percent) of NRA
members supported requiring background checks for all gun sales. (The
margin of error was seven points.)
