The Democratic presidential candidates' silence is part of a pattern. For years, the national party has downplayed its historic sympathy for gun control for fear that emphasizing it would be politically costly.
When Obama first ran for the Illinois Senate 12 years ago, he answered "yes" to whether he backed banning the manufacture, sale and possession of handguns in the state.
He's softened that position in recent years. When she was asked why Obama didn't sign one of the Supreme Court briefs, campaign spokeswoman Jen Psaki said, "Barack Obama believes the Second Amendment creates an individual right, and he greatly respects the constitutional right of Americans to bear arms."
Clinton has a long history as an outspoken supporter of tough gun-control measures, but she, too, has moderated in recent months; last month in Wisconsin, she described how she once went hunting in Arkansas and shot a banded duck.
At a January debate, she called herself a "political realist, and I understand that the political winds are very powerful against doing enough to try to get guns off the street."
