The most recent polling, however, indicates just over half of Americans nationwide think gun control laws should be stricter. According to a CBS/New York Times Poll from early June, 51 percent of Americans favor stricter regulations, while 47 percent prefer laws are kept as they are or become less strict.
Numbers in favor of tighter gun laws have dropped since the days following the Sandy Hook shooting.
Mark Glaze, director of the Michael Bloomberg-backed group Mayors Against Illegal Guns, thinks the Navy Yard shooting will have an impact on the larger debate, even if the effects aren't immediate.
"It is the Chinese water torture of a series of mass shootings that are happening more rapidly and are growing more deadly," he said.
His group will hold a previously scheduled rally Thursday on Capitol Hill, with protests specifically aimed at senators who voted against the background check proposal.
