Addressing supporters at an election watch party on Tuesday night, Rep. Lucy McBath, the projected winner in Georgia's 7th Congressional District, used the moment to discuss gun violence after a mass shooting at an elementary school left at least 19 children and two adults dead in Uvalde, Texas.

"Tonight I came to give one speech but I am now forced to make another," McBath said after briefly thanking voters and volunteers, "because just hours ago, we paid for the weapons of war on our streets again with the blood of little children sitting in our schools."

McBath rose to national prominence in 2018, becoming a leading advocate for gun control after her son, Jordan, was shot and killed at a gas station in Florida. She described on Tuesday night the "all-consuming fear" that parents feel about their children’s safety.

"The violence that took my soon has been replayed with casual callousness and despicable frequency," McBath said, citing the recent shooting at a grocery store in Buffalo, New York, that left 10 people dead, as well as past tragedies in Newton, Connecticut, and Charleston, South Carolina.

"We cannot be the only nation where one party sits on their hands as children are forced to cover their faces in fear," McBath said. "We are exhausted, all of us, the American majority."

Rep. Lucy McBath will win the Democratic nomination in Georgia’s 7th Congressional District, ABC News has projected, besting Rep. Carolyn Bourdeaux after redistricting pitted the two incumbents against each other.

McBath flipped Georgia’s 6th Congressional District from red to blue in 2018. She is now the presumptive front-runner to win the November general election in the solidly Democratic district, which includes the Atlanta suburbs.

Her primary win comes on the same day as a mass shooting at an elementary school in Texas. McBath has been advocating for gun control following the death of her son, Jordan Davis, from gun violence back in 2012. He was shot and killed at a gas station in Florida by a man who complained that his and his friend's music was too loud.

In a statement, McBath said Tuesday that we as a country our better than this and that it is "imperative we act, and act now."

Former President Donald Trump called into Herschel Walker's victory party on Tuesday night, congratulating the Republican nominee in brief remarks.

"And, you know, you were the greatest football player, and you'll be an even greater politician and Senator," Trump said.

"I knew it right from the beginning when first I spoke to you and I said, this man is gonna do things that are incredible."

Walker then thanked his campaign and supporters and made a vague jab at his opponents.

"If you live in the state of Georgia, you're my family. And these radicals will have to come after me before they get to you. And I won't let that happen," Walker said.

ABC News projects that Sarah Huckabee Sanders will win the Republican nomination for governor in Arkansas, beating out her sole competitor, Little Rock radio host Francis "Doc" Washburn.

Sanders, the 39-year-old daughter of former Gov. Mike Huckabee, with her victory upholds a political dynasty in Arkansas. Heading into Election Day, she secured endorsements from former President Donald Trump, former Vice President Mike Pence and Sen. Tom Cotton, among others.

Trump made his last push for Sanders today, sending wide a statement called his endorsee a “warrior” who would do what is right, not what is "political correct."
