Former President Donald Trump returns Saturday to Georgia, which he lost four years ago, to campaign in a state that Democrats and Republicans see as up for grabs yet again.

Trump's 5 p.m. event alongside his running mate, Ohio Senator JD Vance, comes just days after Vice President Kamala Harris rallied thousands in the same basketball arena at Georgia State University in Atlanta.

Both parties are focusing on Georgia, a Sun Belt battleground that Democrats had signaled just two weeks ago they would sideline in favor of a heavier focus on the Midwestern “blue wall” states. President Joe Biden's decision to end his campaign and endorse Harris fueled Democratic hopes of an expanded electoral map.

“The momentum in this race is shifting,” Harris told a cheering, boisterous crowd on Tuesday. “And there are signs Donald Trump is feeling it.”

Biden beat Trump in the state by 11,779 votes in 2020. Trump pressured Georgia's Republican Secretary of State Brad Raffensperger to “find” enough votes to change the outcome. Trump was later indicted in Georgia for his efforts to overturn the election, but the case remains on hold while courts decide whether the Fulton County district attorney can continue to prosecute it.

In announcing Saturday's rally, the Trump campaign accused Harris of costing Georgians money due to inflation and higher gas prices, which have risen from pandemic-era lows at the end of the Trump administration. The campaign also noted the case of Laken Riley, a nursing student from the state who was killed while jogging in a park on February 22. A Venezuelan citizen has been indicted on murder charges in her death.

Trump and his allies have repeatedly labeled Harris the current administration's “border czar,” a reference to her assignment leading White House efforts on root causes of migration.

But in recent days, Trump has lobbed false attacks about Harris' race and suggested she misled voters about her identity. Harris has stated for years in public life that she is Black and Indian American.

At her rally in Atlanta, Harris called Trump and Vance “plain weird” — a lane of messaging seized on by many other Democrats of late — and taunted Trump for wavering on whether he’d show up for their upcoming debate, currently on the books for September 10 on ABC.

Saying earlier that he would debate Harris, Trump has more recently questioned the value of a meetup, calling host network ABC News “fake news,” saying he “probably” will debate Harris, but he “can also make a case for not doing it.”

The fact that Harris and Trump have been focusing resources on Georgia underscores the state's renewed significance to both parties come November. Going to Atlanta puts Trump in the state's largest media market, including suburbs and exurbs that were traditional Republican strongholds but have become more competitive as they've diversified and grown in population.

In a strategy memo released after Biden left the race, Harris campaign chair Jen O’Malley Dillon — who held the same role for Biden — reaffirmed the importance of winning the traditional Democratic blue wall trio of Michigan, Wisconsin and Pennsylvania but also argued that Harris' place atop the ticket “opens up additional persuadable voters” and described them as “disproportionately Black, Latino and under 30” in places like Georgia.

Next week, along with her eventual running mate, Harris plans to visit that Midwestern trifecta, along with North Carolina, Arizona and Nevada. On Friday, she will make another stop in Georgia.
