Senate Democrats launch first ad in Mississippi as their midterm optimism spreads to the South

WASHINGTON (AP) — Senate Democrats' top campaign spending group is wading into Mississippi's U.S. Senate race for the first time this year, an aggressive move in a deep-red state that signals a party on the offensive as Republicans look to protect a slim majority.

The Senate Majority PAC will spend $1.2 million on a new television advertisement to boost Scott Colom , a district attorney, in his campaign against Republican Sen. Cindy Hyde-Smith. The ad, first disclosed to The Associated Press, is set to start Wednesday and run through Election Day.

“Senate Majority PAC has been watching this race closely, and it is clear Colom is running a competitive race that has put Hyde-Smith on her heels,” group spokesperson Lauren French said in a statement.

With just two weeks to go in the race, it's unclear what impact the ad will have in a matchup that's been set since Colom won a March primary . Still, it's a substantial investment in a race that's seen only about $8 million in total spending, with Colom outspending Hyde-Smith nearly $4.6 million to $3.2 million, according to AdImpact.

Hyde-Smith, first appointed and then elected in 2018 , is running for reelection in a state Republicans have long dominated. In the 2024 presidential race, Republican Donald Trump won Mississippi by nearly 23 percentage points over Democrat Kamala Harris, and a Democrat hasn’t won a Senate race in the state since 1982.

However, some Democrats believe Hyde-Smith is vulnerable, and she underperformed Trump by 6 percentage points in 2020 , the year he lost his White House reelection bid to Democrat Joe Biden.

The television ad touts Colom's time as district attorney, while labeling Hyde-Smith a “do-nothing” senator.

“A decade in power, Hyde-Smith hasn’t passed one piece of legislation, but she did vote to kick people off Medicaid,” a narrator says in the ad, which will run on television stations statewide alongside a digital campaign.

The AP was reaching out to Hyde-Smith’s campaign for comment.

Colom has raised Democratic hopes in a year when electoral winds are at their backs. Georgia Sen. Raphael Warnock was the latest high-profile Democrat to campaign with Colom last week, and Harris, who was Biden's vice president, is set to rally with Colom on Thursday.

Republicans currently hold a 53-47 majority in the Senate and were expected to face a friendlier map this year with fewer seats to defend. But high costs and gas prices amid an unpopular war in Iran under a Republican president have made Democrats optimistic, with the Senate Majority PAC spending its final weeks investing in conservative territory. It's already announced spending in Kansas , where megachurch pastor and Democratic nominee Adam Hamilton is trying to unseat Republican Sen. Roger Marshall.

Colom would be his state’s first Black senator since Reconstruction, the 12-year period after the U.S. Civil War when the 13th, 14th and 15th Amendments were adopted.

Some Democrats have criticized national groups for not spending more in Southern states like Mississippi.

“I worry, to be very honest, that Democrats are missing a real opportunity to invest in a serious and sustained way in the South,” Warnock said Sunday on NBC’s ”Meet the Press."
