(WASHINGTON) -- From the June 28 debate between President Joe Biden and former President Donald Trump to the Oct. 1 vice presidential debate of Minnesota Gov. Tim Walz and Ohio Sen. JD Vance, at least 134 people were killed in 148 mass shootings across the United States, according to the Gun Violence Archive.
But during those roughly three months and since, the issue of gun violence prevention, according to some advocates, has been overshadowed by a flurry of hot-button campaign topics: The state of the economy, abortion rights, wars raging in the Middle East and Ukraine, two assassination attempts on Trump and the shifting political landscape in which Vice President Kamala Harris succeeded Biden as the Democratic nominee.
"Gun violence is still one of the most important issues facing our country. We still have an ongoing epidemic," said Nicole Hockley, the CEO of Sandy Hook Promise -- a gun violence prevention group she co-founded following the 2012 mass shooting at Sandy Hook Elementary School in Newtown, Connecticut, that left 20 children, including her son, and six adult staff members dead.
In an interview this week with ABC News, Hockley cited a Johns Hopkins Center for Gun Violence Solutions report that said for three straight years gun violence has been the leading cause of death in the United States for adolescents under the age of 19.
In an ABC News/Washington Post/Ipsos poll released in August, gun violence was ranked eighth in importance among voters after the economy, inflation, health care, protecting democracy, crime and safety, immigration and the Supreme Court.
According to a 2023 Pew Research Center survey, 61% of Americans say it's too easy to legally obtain a gun in this country and 58% believe U.S. gun-control laws should be stricter.
"I do appreciate that there are many other large issues and hot topics like the economy, like abortion, like foreign wars that are of interest to voters as well," said Hockley, whose nonpartisan group does not endorse candidates nor donate to campaigns.
She added, "Perhaps there is an assumption, rightly or wrongly, that everyone already knows what each candidate's opinion is and what they are likely to do in terms of gun violence prevention, whereas they might not be as clear on things like policies around the economy."
Debates over gun violence
During the three national debates in the presidential campaign, the subject of gun violence prevention appears to have received less discussion compared to the other contentious topics, some advocates said.
In the Sept. 10 debate between Harris and Trump, hosted by ABC News, gun violence came up when Trump -- who was shot in the ear during a July 13 assassination attempt in Butler, Pennsylvania, that left one campaign rallygoer dead and two others wounded -- alleged, "She wants to confiscate your guns."
The accusation prompted Harris, who oversees the first-ever White House Office of Gun Violence Prevention, to respond, "Tim Walz and I are both gun owners. We're not taking anybody's guns away. So stop with the continuous lying about this stuff."
Harris, the former California Attorney General, also said, "I'm the only person on this stage who has prosecuted transnational criminal organizations for the trafficking of guns, drugs and human beings."
Ten days after debating Trump, Harris reiterated that she is a gun owner during a televised sit-down interview with Oprah Winfrey, adding, "If somebody breaks in my house, they're getting shot."
The most extensive conversation on guns during the debates came during the vice presidential debate when Walz touted his record in Minnesota on combating gun violence, saying his administration had passed an assault weapons ban and enhanced red-flag gun laws to keep weapons out of the hands of people poised to harm themselves or others.
"These are reasonable things that we can do to make a difference," Walz said about gun violence prevention during the debate.
Vance and Trump oppose most gun-control laws, including an assault weapons ban and national red-flag laws proposed by Harris. The National Rifle Association has endorsed the Trump-Vance ticket.
"Now, more than ever, freedom and liberty need courageous and virtuous defenders," Doug Hamlin, executive vice president and CEO of the NRA, said in a statement in July. "President Trump and Senator Vance have the guts and the grit to stand steadfast for the Second Amendment."
During the debate, Vance said on gun violence prevention measures, "Governor Walz and I actually probably agree that we need to do better on this."
Addressing school shootings, Vance said at the debate, "I, unfortunately, think that we have to increase security in our schools. We have to make the doors lock better. We have to make the doors stronger. We've got to make the windows stronger. And of course, we've got to increase school resource officers because the idea that we can magically wave a wand and take guns out of the hands of bad guys, it just doesn't fit with recent experience."
'The lockdown generation'
Angela Ferrell-Zabala, executive director of Moms Demand Action, a grassroots movement of Americans fighting for public safety measures, said that despite the myriad issues in this campaign cycle, gun violence prevention still resonates with voters nationwide.
"First and foremost, I get to travel all across this country and meet with our volunteers and partners and candidates running up and down the ballot, and there are so many people that are not running away from this issue but running on it and actually winning," Ferrell-Zabala told ABC News. "This is a priority for many folks."
She said that from her experience, young people, who have grown up in the era of school lockdowns and active shooter drills, are particularly energized over the issue of gun violence prevention and plan to vote their conscience.
"This is a big issue. This is a top three for all voters and for young people, this is particularly hitting them because they are the lockdown generation. Many of them are survivors of gun violence themselves," said Ferrell-Zabala, whose group has endorsed the Harris-Walz ticket.
According to the 2023 Pew Research Center survey, 88% of respondents also favored preventing mentally ill people from buying guns and 79% wanted the minimum age for buying guns raised to 21.
Ferrell-Zabala said most aspects of gun violence prevention should not be considered political, including requiring gun owners to secure their weapons to prevent them from falling into the hands of children or people intent on harming others or themselves.
"They are being used as political issues, but they are not. The majority of people, polls show time and time again, are for common sense gun laws because they know they are going to save lives in this country," Ferrell-Zabala said. "And what you're seeing is a product of a gun industry and extremist politicians that are trying to back this guns-everywhere culture, where guns are everywhere for anyone anytime. That's unacceptable, frankly."
Hockley said that many of the children who survived the Sandy Hook massacre that claimed the life of her 6-year-old son, Dylan, have now reached the age of 18 and will be voting in their first presidential election.
"I believe that they will be very much voting to stop this epidemic," Hockley told ABC News. "I'm sure they'll have other concerns as well, women's rights, human rights. Gun violence prevention is also a human right, the right to live to your full potential. These students have seen the worst of what our country can offer in terms of school violence and I very much believe and hope that they will be voting that as one of their main issues."
