In the months following the tragedy, President Obama and Democrats failed to push through a gun control package that would have increased regulation on gun trafficking and provided universal background checks, among other things. 

Proposals to ban semi-automatic assault rifles and large ammunition magazines also failed in the Senate. 

Obama did enact a number of smaller proposals through executive order earlier this year. Among them were plans to provide incentives for schools to hire resource officers from the law enforcement community and fund training to first responders to handle armed attacks. 

Obama will announce two new executive orders Thursday and swear in B. Todd Jones to lead the Bureau of Alcohol, Tobacco, Firearms and Explosives. 

While the Sandy Hook shooting took place in a town of about 30,000, parents living in big cities are more likely to fear for their child’s safety.  Nonwhites and parents with an income less than $50,000 express the most concern, according to Gallup. 

The number of concerned parents reached its peak in 1999 after the shooting at Columbine High School. It took nearly two years for those numbers to drop down to normal levels. 

The poll surveyed 508 parents of children in kindergarten through 12th grade. It has a sampling error of plus or minus 5 percent.
