NEW YORK (AP) — Support for tougher gun control laws is soaring in the United States, according to a new poll that found a majority of gun owners and half of Republicans favor new laws to address gun violence in the weeks after a Florida school shooting left 17 dead and sparked nationwide protests.

The poll, conducted by The Associated Press-NORC Center for Public Affairs Research, found that nearly 7 in 10 adults now favor stricter gun control measures. That's the strongest level of support since The Associated Press first asked the question five years ago. The new poll also found that nearly half of Americans do not expect elected officials to take action.

"It feels hopeless," said 30-year-old Elizabeth Tageson-Bedwin, of Durham, North Carolina, a self-described Republican who teaches 7th grade English. "Considering recent events, gun control in this country needs to be stricter — and it can be without infringing on anyone's rights."

Overall, 69 percent of Americans think gun laws in the United States should be made stricter. That's up from 61 percent who said the same in October of 2016 and 55 percent when the AP first asked the question in October of 2013. Overall, 90 percent of Democrats, 54 percent of gun owners and 50 percent of Republicans now favor stricter gun control laws.

Sixty percent believe that making it harder to legally obtain a gun would result in fewer mass shootings; just 49 percent said the same in the 2016 poll.

The new poll finds support for specific gun control measures even among those who bristle at the term "gun control."

"That's what Hitler did," said Flora McIntyre, of Simi Valley, California, repeating a common, but inaccurate, line of criticism against gun control measures. "Hitler made everyone register their guns. Then he came and collected all the guns."

But when asked about specific gun control prescriptions, the 82-year-old retired nurse, who said she owns a rifle and a .44 Magnum, said she favored stronger background checks and limits on the number of bullets allowed in a gun magazine. She also opposes President Donald Trump's plan to give guns to trained teachers.

The poll shows that McIntyre is not alone.

More than 8 in 10 Americans favor a federal law preventing mentally ill people from purchasing guns, along with a federal law expanding background check requirements to include gun shows and private sales.

Nearly 8 in 10 favor allowing courts to prevent people from owning guns if considered a danger to themselves or others, even if they have not been convicted of a crime. And 7 in 10 favor a nationwide ban on devices known as "bump stocks" that allow semi-automatic guns to function like automatic guns.

Nearly 6 in 10 favor a nationwide ban on AR-15-style rifles.

"They should take them off the market. Too much power right there," 25-year-old Sedrick Clark, of St. Louis Missouri, said of AR-15s.

Clark, a self-described Republican, said he recently purchased a handgun for protection. But he said he'd support police efforts to go door-to-door to confiscate "dirty guns" from convicted felons and others who shouldn't have them.

"I know Trump would do it," Clark said, praising the Republican president.

Americans have mixed views on whether they expect any elected leaders to enact tougher gun control laws in the next year.

The Florida legislature passed a law earlier in the month to raise the minimum age to purchase a firearm to 21. The law also extended the waiting period to three days, banned "bump stocks," funded more school police officers and mental health services, and allowed certain staff members to carry guns in schools. Congress, however, has yet to adopt new gun control measures that would apply to the rest of the country.

Just over half of Americans — 51 percent — expect elected officials to tighten gun laws, while 42 percent expect no changes; another 6 percent expect gun laws to be made less strict. Nearly two-thirds of Republicans, but less than half of Democrats, predict gun laws will be made stricter.

Democrat Cody Campbell, a 42-year-old IT worker from Atlanta, suggested that the financial impact of the gun industry would prevent meaningful change.

"Here in the U.S., it's all about the money, and guns are a big part of how we make money," said Campbell, a gun owner who supports stronger gun control.

In Florida, not far from where a 19-year-old gunman killed 17 people and wounded 17 others last month, 50-year-old John Karnosh said he's favored stricter gun control measures since the 1999 school shooting in Colorado's Columbine High School that left 15 dead.

"All this time has passed and still nothing has changed," said Karnosh, a gun owner from Miramar, Florida, who is not registered with either party. "I live in the same county, down the street from Parkland. I see what these kids are doing. If anyone can build a movement for change, these kids will do it."

The AP-NORC poll of 1,122 adults was conducted March 14-19 using a sample drawn from NORC's probability-based AmeriSpeak Panel, which is designed to be representative of the U.S. population. The margin of sampling error for all respondents is plus or minus 4.2 percentage points.

Respondents were first selected randomly using address-based sampling methods, and later interviewed online or by phone.
