SCOTT SIMON, HOST:
This week, some of the victims of that shooting rampage at a Colorado movie theater were laid to rest. In the days following the attack, the country's political leaders offered expressions of sorrow for the lives lost. But none moved to rewrite laws in hopes of preventing such massacres. Election-year politics may be one explanation.
But as NPR's David Welna reports, another may be the sway one interest group holds over Congress.
DAVID WELNA, BYLINE: Earlier this week, Colorado congresswoman Diana DeGette joined three other Democratic lawmakers at the Capitol to make a plea.
REPRESENTATIVE DIANA DEGETTE: We don't believe that the Second Amendment guarantees somebody the right to walk into a movie theater with a semiautomatic weapon and a 100-round ammo magazine and shoot 71 people. We don't believe that. And we believe that we need to have a national conversation.
WELNA: One that the Denver-based Democrat hoped would begin on Capitol Hill, but there's virtually no chance such conversation would lead to action. Here's John Boehner, the Republican House speaker on Thursday, when asked whether new laws were needed to prevent another gun slaughter.
REPRESENTATIVE JOHN BOEHNER: No. I think that what's appropriate at this point is to look at all the laws that we already have on the books to make sure that they're working as they were intended to work.
WELNA: On the other side of the Capitol, Senate Democratic Leader Harry Reid was also giving a thumbs down.
SENATOR HARRY REID: With the schedule we have, we're not going to get into a debate on gun control.
SENATOR FRANK LAUTENBERG: The silence is almost deafening.
WELNA: That's New Jersey's Democratic Senator Frank Lautenberg. He blames the four-million-member National Rifle Association for stifling any congressional action on guns.
LAUTENBERG: And we cannot let the NRA stop us from commonsense reforms anymore.
WELNA: Gun-control advocates say the NRA's power cannot be overestimated.
MIKE CASTLE: I believe the NRA has as much sway on Capitol Hill as any lobbying group in the country.
WELNA: Mike Castle, a former Republican congressman from Delaware.
CASTLE: They've done a very effective job of convincing people that - whether it's true or not - convincing people that, you know, they have the power to completely limit their futures in elected office, if they don't cooperate.
WELNA: Most recently, the NRA has been weighing in on an ongoing fight between Republicans and Attorney General Eric Holder, regarding a gun-tracing operation known as Fast and Furious.

UNIDENTIFIED MAN: Did America's top prosecutor commit perjury before Congress? Call the president, tell him to fire Eric Holder. Paid for by the men and women of the National Rifle Association.
WELNA: When the House moved late last month to hold the attorney general in contempt of Congress, the NRA announced the vote would count in its ratings of lawmakers. Seventeen Democrats joined all but two of the House Republicans in approving the contempt citation.
Here's NRA legislative director Chris Cox after that vote.
CHRIS COX: So my hat's off to those Democrats who bucked their party, bucked their president and put truth and justice over politics.
WELNA: Minnesota's Tim Walz has an A-rating with the NRA. He's one of the Democrats who voted to hold the attorney general in contempt. Did he fear the NRA might work against his re-election bid this fall had he voted differently?
REPRESENTATIVE TIM WALZ: No, I can't say whether they would've or not. But again, I would have to assume that that very well could've happened.
WELNA: But some say the NRA's power has been vastly overestimated. Mark Glaze directs the advocacy group Mayors Against Illegal Guns.
MARK GLAZE: People are hard-pressed to find more than a handful of members of Congress who have ever lost their seat because of the NRA, or because of a gun vote. But the NRA has spent a lot of money and a lot of years building up that very reputation, and a lot of Democrats have bought into it.
REPRESENTATIVE GERRY CONNOLLY, DEMOCRAT, VIRGINIA: I'm not intimidated by anybody.
WELNA: House Democrat Gerry Connolly has the NRA's headquarters in his Northern Virginia district. Nonetheless, his advocacy of stricter gun laws has helped him win re-election. Still, Connolly understands how many colleagues bend to a reality of politics.
VIRGINIA: That which is perceived is also real. So, the power exercised here certainly by the NRA is considerable.
WELNA: The NRA declined to comment for this story and declined.
