AUSTIN — The shooting at Santa Fe High School does not appear to have changed the minds of Texans who support or oppose stricter gun laws, a new Quinnipiac University poll released Thursday shows.

According to the poll, which was conducted the week after the shooting, 49 percent of Texans support stricter gun laws in the U.S., while 45 percent oppose it. In an April poll asking Texans about gun laws, 55 percent supported stricter regulations while 41 percent opposed it.

"The tragedy at the Santa Fe school south of Houston changed few opinions among Texas voters about gun control," Peter Brown, assistant director of the Quinnipiac Poll, said in a news release. "Support for gun control in general is down slightly, while support for background checks for all gun buyers is virtually unchanged."

Despite the decrease in surveyed voters supporting stricter gun laws, Brown said the number was only slightly significant, and it's hard to tell if the Santa Fe shooting affected the numbers.

"Most people would say after a tragedy like Santa Fe, if there's going to be a change, that change would favor stricter gun control and that's not what we found," he said.

More than 90 percent of Texans — gun owners or not — support universal background checks for gun buyers.

Texans also seem to favor more armed personnel at schools, Brown said.

"While 51 percent of Texas voters want to arm teachers and other school officials, 87 percent of voters want armed security officers in the schools," he said.

Ed Scruggs, board vice chairman for the advocacy group Texas Gun Sense, said the slight decrease in support for gun control could be attributed to Texas' unique culture.

"Overall, it is a mild drop," he said. "There is still a significant amount of support for stricter gun laws. The support for background checks for all gun buyers really didn't move at all, which indicates sustaining strength for doing more. If it were a bigger drop, I'd be more worried."

Scruggs said he wants to see the next few polls to look for trends, as each day has the potential for another incident that could change Texans' answers.

"It's more interesting to look at trends over the next three to four months rather than a snapshot," he said. "But the poll does show there is a continued solid block of folks in support of stricter gun laws."

The poll surveyed 961 self-identified registered voters, with 34 percent identifying as Republican, 23 percent as Democrat, 34 percent as independent, and 9 percent as "other." The poll reported a 3.8 percent margin of error.

Following the attack in Santa Fe, where a student killed 10 people and injured 13 more with a shotgun owned by his father, Gov. Greg Abbott conducted three days of roundtable discussions at the Capitol. On Wednesday, he released a 40-plus page document of recommendations for school safety, including reducing the number of entrances to schools, increasing the presence of school marshals, expanding active shooter training and providing counseling for students.

"Leaders in schools want to keep students safe," Abbott said Wednesday. "It doesn't take a mandate from the state of Texas."

Meanwhile, Lt. Gov. Dan Patrick called for arming teachers in a one-minute radio ad released Tuesday, before Abbott unveiled his recommendations for school safety. Patrick also blamed school violence on a culture that "removed God from our schools, devalued life through abortion, the break up of families and violent video games and movies that desensitize our kids to violence."

Quinnipiac University also published poll results Wednesday showing Texas Sen. Ted Cruz with a 50 percent to 39 percent edge over the El Paso congressman vying to replace him, Rep. Beto O'Rourke. The gap between the two candidates has widened since the April Quinnipiac poll, in which pollsters said the race was "too close to call."
