Another new poll shows support for stricter gun control measures has fallen significantly since the push failed in Congress earlier this year.

The CNN/Opinion Research poll shows 49 percent now support stricter laws — down from 55 percent in January (shortly after the shootings at an elementary school in Newtown, Conn.) and from 53 percent in April. Half of Americans (50 percent) say they oppose stricter gun laws.

The findings echo Gallup's polling, which has shown a similar dropoff.

The Newtown tragedy was back in the news Wednesday, as audio recordings of that day's 911 calls were released.

The White House has suggested it might try again to push new gun laws — particularly increased background checks — but so far there has been little impetus for a retry in Congress.
