NEWTOWN, Conn. (AP) — Having already lost her 6-year-old son, Nicole Hockley insists she won't lose the fight to reduce gun violence — no matter how long it takes.

She is among a group of "accidental activist" parents brought together one year ago by almost unthinkable grief after the Newtown school massacre. The shootings were so horrific that many predicted they would force Congress to approve long-stalled legislation to tighten the nation's gun laws.

They did not.

A divided Congress denied President Barack Obama's calls for changes. The national gun lobby, led by the National Rifle Association, is arguably stronger than ever. And surveys suggest that support for new gun laws is slipping as the Newtown memory fades.

A new Associated Press-GfK poll finds that that 52 percent of Americans favor stricter gun laws, while 31 percent want them left as they are and 15 percent say they should be loosened. But the strength of the support for tighter controls has dropped since January, when 58 percent said gun laws should be tightened and just 5 percent felt they were too strong.
