Gun-control activist Lucy McBath, whose teenage son was shot and killed in 2012 by a stranger at a gas station, won the Democratic nomination for Georgia's 6th Congressional District.
"I am at a loss for words. Thank you to my supporters, friends & family. And I want to thank my dear Jordan, my rock & inspiration," McBath tweeted after the race was called. Her son, Jordan, was 17 when he was killed.
A former flight attendant and spokesperson for Everytown for Gun Safety, McBath decided to run for Congress in March, after the shooting in Parkland, Florida. Over the course of her campaign, she received influential endorsements of several prominent Democrats, including Sens. Kamala Harris, D-Calif., and Kirsten Gillibrand, D-N.Y., and Rep. John Lewis, D-Ga.
On Tuesday, she beat fellow Democrat Kevin Abel by about 2,000 votes in a runoff election after no candidate hit the 50 percent mark in the Democratic primary race in May.
McBath will now face Republican Rep. Karen Handel in the general election.
Turning from tragedy to politics
McBath would also make history if elected -- she would be the only black woman in Georgia's congressional delegation -- but maintains that she never saw a foray into politics in her life plan.
"I never expected this to happen, but I know that in light of all my experiences, to not to do anything is a tragedy in itself," McBath said in an interview with ABC News just days before the May primary -- and just days after the nation watched another deadly high school shooting unfold in Santa Fe, Texas.
It was the sixth fatal school shooting since the attack in Parkland. When it happened, McBath was on the campaign trail in Georgia. And she knew what the parents were going through.
"I was just as angry and devastated ... with Santa Fe as I was for Parkland because Jordan was the same age as all these children that have been gunned down," she said.
Now, McBath is part of a growing movement: Parents who've lost a child to gun violence deciding to run for office.
"I'm sure you'll continue to see more parents like myself who are losing their children standing up," McBath said. "It's just going to happen."
“We know the eyes and ears of the nation are here, we’re really trying to make sure that democracy works here in our state and make sure that it works for everybody,” McBath said in May.
“At least I am,” the candidate added with a laugh.
According to the most recent FEC filing earlier this month, McBath had just over $151,100 heading into the runoff. Handel, the incumbent, heads into the general with more than $1 million.
Everytown for Gun Violence has played an active role in McBath's campaign, dropping at least $1 million in support of the candidate. McBath's nomination in the red state comes at a time when Georgia faces more firearms deaths than the national average.
In 2016, 1,571 people died in Georgia from firearms, according to the Centers for Disease Control and Prevention -- bringing the rate of deaths to 15 per every 100,000 residents. The national average in 2016 was 11.8 per 100,000.
What she is against, she said, is people who “want to use their guns in a way that is criminal.”
“We have to get a grip on keeping the guns out of hands of people who should not have them,” McBath said.
Throughout her campaign, she’s tried to push back on claims that she’s a one-issue candidate. Knowing what it's like to lose a son, she said, she can understand other issues that hurt families -- such as immigration and the fear of losing someone to deportation.
“I know what it's like to tear families apart from gun violence -- we shouldn’t be doing that with immigration,” McBath said.
Other parts of her platform are inspired by her experience raising her son and being a single mother. At one point, she was so disappointed in the education system she decided she had to homeschool him.
“I recognized my neighborhood wasn't going to be able to give Jordan the education I wanted him to have,” she said.
“So, yes, guns is a huge part of my platform,” McBath said. “But it's not the only part of my platform because a lot of what I’m talking about I’ve experienced myself. That’s been my reality.”
Editor's note: Karen Handel is the first Republican woman to represent Georgia. An earlier version of this story said she was the first woman.
