In the wake of the Connecticut school shootings, there's been plenty of discussion about gun control. But how long will that last?

Dylan Byers put together this chart that illustrates a fairly intuitive point. There's typically a flurry of news items about gun control right after a particularly horrific mass shooting. But the media's interest usually wanes after a month or two:

Nexis mentions of "gun control" in 2012.

Put this together with polls showing that most Americans' opinions on gun laws remained virtually unchanged after the movie-theater shooting in Aurora, Colo. Indeed, even as mass shootings in the United States have become more frequent in recent years, support for gun control has declined (at least in the abstract, though some specific policies, like background checks, do poll well).

On top of that, all the recent political momentum in the United States has been in favor of expanding gun rights, not restricting them. That's been true even though 6 of the 12 deadliest shootings in U.S. history have taken place since 2007. Here's Dave Weigel with the legislative scorecard:

The 2010 Republican wave allowed a series of stalled bills to sail through the states. In 2011, Kansas and Nevada made it legal to "purchase long guns in non-contiguous states," Wyoming passed a "permitless carry" law, Arizona, North Dakota and Kentucky made it easier for people who'd lost their gun rights due to "mental illness committments" to get those rights restored. Maine, Texas, Indiana and North Dakota made it legal for gun owners to keep their weapons in their cars. Oklahoma and Alabama protected their citizens from "illegal gun raids."

What we still don't know is whether this time will be any different. For more on what political scientists have learned about public opinion on guns, see this post by John Sides.
