Four gun measures are slated to be voted on today by the Senate Judiciary Committee and the votes will give some clues as to the fate of tougher gun control laws in Congress as both sides claim growing support for their views.

The horror of the Sandy Hook massacre of 20 6- and 7-year-olds in Newtown, Connecticut, in December shaking the nation to its core. Many thought the momentum had finally swung to push lawmakers to ban assault weapons and add some beef to background-check regulations and the sale and possession of guns. The White House is leading the charge for changes in federal gun laws. Even notorious graffiti artist Shepard Fairey designed a controversial new T-shirt with the proceeds going to support gun control groups.

Yet even though it’s been only a few short months, it seems the memory of Sandy Hook is beginning to fade and the gun supporters lobby has found its legs and voice once again. The pro-gun lobby retains its powerful standing and many think it will mute aggressive gun control measures.

The New York Times has a piece about a little known nonprofit called the Congressional Sportsmen’s Foundation, which arranges shooting contests and wine tastings – hopefully not at the same time – between members of Congress and representatives of the gun industry. Among the biggest recipients of the nonprofit’s largesse are the 250 congressmen who belong to the Congressional Sportsmen’s Caucus.

More and more, voters will see studies such as the one featured in the Boston Globe today from the JAMA Internal Medicine journal. Researchers from Children’s Hospital in Boston examined gun-related deaths in all 50 states and concluded those states with stricter gun laws had fewer gun deaths than states with loose regulations. Massachusetts, which most agree has the nation’s toughest gun laws, has a rate of 3.4 gun-related deaths per 100,000 residents, second only to Hawaii. The highest rate was Louisiana, which had 17.9 gun deaths per 100,000 residents. The same story runs out a study from 2000 by Georgetown University researchers that found states with background checks mandated by the Brady Bill had fewer suicide and homicide rates.

In Connecticut, Quinnipiac University released a new poll that showed overwhelming support for tighter gun control laws. Some measures, such as universal background checks, got the support of 89 percent of gun owners. The public support, though, has done little to push forward a bipartisan attempt in the Nutmeg State to enact tighter gun control legislation, despite Connecticut  being the site of one of the country’s bloodiest gun massacres in history.

In Maryland, lawmakers are set to pass one of the country’s strictest gun laws, including provisions barring gun magazines over 10 rounds and banning 45 assault-type weapons. The Maryland proposal has prompted a threat from the nation’s biggest gun manufacturer, Beretta USA, to close its factory there and move its 400 jobs elsewhere if the measure is signed into law. As expected, Texas Gov. Rick Perry has already rolled out his state’s welcome mat.
