In late May, 18-year-old gunman Salvador Ramos entered Robb Elementary School in Uvalde, Texas, and gunned down 19 students and two teachers. Ramos was later killed by police after they gained entry into the school after waiting more than an hour to enter, sparking widespread criticism about the lack of response officers had.

The ad shows Abbott discussing his administration’s law easing restrictions on guns. “Remember when we passed open carry and campus carry and people said it was going to be the OK Corral? None of that happened,” Abbott is seen saying in the ad. It then continues with surveillance footage inside the school showing Ramos walking the hallways holding his gun. “I don’t think there is going to be any bad side effect to it,” Abbott continues saying about the law.

A person with “No It Couldn’t,” the group behind the new ad, told Newsweek on Sunday, “We want people to remember what happened and maybe this could bring some energy to voters.”

The ad also featured a 911 call that a student made inside one of the classrooms during the mass shooting, who told operators to “hurry” and that there were “a lot of dead bodies.”

“The little girl’s 911 call juxtaposed with Abbott’s cavalier attitude shows that actions have real consequences,” the person, who did not want to be named, with “No It Couldn’t” added.

Meanwhile, political analyst Craig Agranoff told Newsweek on Sunday that Republicans “tend to take the religious approach with more God in schools. Many people are beyond tired of the thoughts and prayers approach.” Agranoff added that the new ad doesn’t stop Abbott’s momentum, however.

“He is far ahead in the polls. He’s like a Teflon candidate,” he said.

In the latest University of Texas at Tyler poll from mid-October, Abbott retains a 6-point lead ahead of his Democratic challenger Beto O’Rourke. The poll sampled 1,330 people and has a 2.9 percent margin of error. The top issues voters are facing in the state are securing the U.S.-Mexico border, inflation, reproductive rights and gun control, according to the poll.

“Republicans play well with evangelicals and Second Amendment believers,” Agranoff said. “It is easy to have either of them switch and vote with the candidates who share their beliefs.”

Brett Cross, whose child was killed in the mass shooting, took to Twitter on Sunday to denounce Texas Senator Ted Cruz, a Republican, who took a photo of himself and his daughter enjoying the Houston Astros play in the World Series.

“Sure wish I could have taken my son to see the Astros win the World Series. Oh that’s right, he was slaughtered. While you sit there and enjoy these games while supporting bills that lead to easier access…to obtain these weapons,” Cross tweeted.

He has also voiced anger towards Cruz and Abbott in the past calling them “cowards,” claiming that they “run away during tragedy.”

As part of the Texas Rangers’ investigation into the school shooting, a Texas doctor said on Thursday that he is investigating with Texas State Police to see whether any of the victims could have survived if medical help arrived sooner.

It is unclear if this investigation will impact the states’ criminal investigation, but the goal is to have the lessons learned applied to policy around the country, Austin’s Chief Medical Examiner Dr. Mark Escott said.

Newsweek reached out to Abbott’s campaign for comment.
