Compared with the amount spent by pro-gun groups over the years, expenditures by gun safety groups are a pittance.
As the Center for Responsive Politics reports: The gun rights lobby spent $75 million from 1998 through 2012.
Nevertheless, funding for gun control has increased dramatically. Spending by Mayors Against Illegal Guns, the major gun safety lobby in Washington, totalled just $200,000 in 2012. Spending this year has soared to $830,000.
