"I don't want to go their cocktail parties. I don't want to make friends. I just don't want them to stop Americans of their rights including me and my kids," said Dudley Brown, executive director of Rocky Mountain Gun Owners.
His group, as well as pro-gun rights groups and publications, such as Concealed Carry magazine, have stepped up gun giveaways in states like Colorado, New York and Arizona, where tough gun control laws have passed or are pending.
The National Rifle Association, the nation's largest and most powerful gun lobby group, said Wednesday that expanding background checks at gun shows "will not prevent the next shooting, will not solve violent crime and will not keep our kids safe in schools."
The group's leaders have also been deeply critical of Obama's efforts.
"President Obama should be as committed to dealing with the gang problem that is tormenting honest people in his hometown as he is to blaming law-abiding gun owners for the acts of psychopathic murderers," the NRA said in a statement.
Obama has often said that the fight for new gun control is personal.
He wiped away tears when reflecting on the Newtown shooting spree. And the president was animated in talking about what he sees as national support for stricter gun control policies.
However, gun control advocates have worried and polls have shown that in the months following the Newtown shooting, support for stricter gun laws has waned.
In that, Obama's fierce push to keep the issue up front has been extremely valuable to those seeking stricter gun laws, Spitzer said.
"It's an imperative that the president be out front on this issue," Spitzer said. "Obama's ability to keep this in the minds of the public paves the way a little more for legislative reforms."
