But polls also show that most Americans favor some expansion of background checks and gun control supporters promise to keep pressing the issue.
Sen. Joe Manchin, a West Virginia Democrat, has said he will re-introduce the bill to require criminal and mental health background checks for gun buyers at shows and online. And despite their loss on the federal level, gun control advocates have scored some significant victories at the state level.
Colorado lawmakers passed new restrictions on firearms, including required background checks for private and online gun sales and a ban on ammunition magazines that hold more than 15 rounds. Connecticut recently added more than 100 firearms to the state's assault weapons ban and now requires background checks for private gun sales.
Maryland and New York have passed sweeping new guns laws, and in Washington state, supporters of universal background checks recently announced a statewide campaign to collect 300,000 signatures to put the issue straight to voters.
"There are 90 percent of Americans that support this," Lafferty said. "We are not going away. It's a huge issue."
