Former President Barack Obama has rolled out a new ad backing Democrat Scott Colom against Sen. Cindy Hyde-Smith in deep-red Mississippi, a long-shot push in a race Republicans are heavily favored to hold.

Obama’s message landed this week as Colom tries to unseat the Republican incumbent, who is seeking a second full term. The Hill reported the former president’s direct pitch to Magnolia State voters.

Mississippi has not sent a Democrat to the U.S. Senate since 1982. Decision Desk HQ’s polling average gives Hyde-Smith a 93 percent chance of keeping the seat, even as the same outfit gives Democrats a 56 percent chance of flipping the chamber nationally.

That gap frames the ad. Obama is inserting national star power into a state that has stayed Republican for more than four decades at the Senate level, while President Trump works red and purple states to help the GOP hold Congress.

Obama’s ad sells Colom as faith-driven prosecutor

In the spot, Obama leans hard on biography and kitchen-table issues. He casts Colom as rooted, religious, and tough on crime.

Obama says in the ad:

"Mississippi, it’s time for a change. That’s why you need to send Scott Colom to the U.S. Senate,"

He continues with personal framing:

"Scott is a devoted husband and dad, a seventh-generation Mississippian, guided by his Christian faith."

The closer ties Colom’s record as a local prosecutor to national Democratic talking points on wages, costs, and hospitals:

"Scott made his community safer, prosecuting violent crimes as district attorney, fighting corruption in Columbus. Now he’s running for Senate to raise wages, lower costs, and save your healthcare and hospitals. Mississippi, your vote matters. Let’s get this done,"

Colom serves as district attorney in Mississippi’s 16th District. The ad presents that résumé as the reason voters should break a four-decade pattern.

Hyde-Smith and Wicker already blocked Colom once

Colom is not a new name to Mississippi’s Republican senators. Former President Biden nominated him twice to serve as a U.S. district judge for the Northern District of Mississippi.

Hyde-Smith and Sen. Roger Wicker blocked those nominations through the Senate’s blue-slip tradition, the long-standing courtesy that lets home-state senators halt lower-court picks. The same lawmakers Colom now wants to join already stopped his path to the federal bench.

That history sits under the campaign rhetoric. A candidate Democrats once tried to place on the bench is now the vehicle for an Obama-branded challenge to one of the senators who said no.

Obama’s midterm involvement fits a wider pattern of the former president stepping back into party fights, including efforts to steer Democrats toward AI as a midterm weapon and other national messaging plays.

Gas prices and the cost pitch land in a red state

The ad’s cost-of-living line meets hard numbers on the ground. AAA put the average price of regular gas in Mississippi at $3.93 as of Monday afternoon, up $1.27 from a year earlier. Diesel averaged $5.87 a gallon, up $2.62 over the same stretch.

Those figures give concrete weight to any “lower costs” appeal. They also arrive while national politics still revolve around energy, inflation, and who owns the results.

Democrats are hunting every opening they can find in Senate map math. In Michigan, party figures have likewise reached for Obama’s brand after messy primaries, with one nominee dialing up Obama as Democrats scrambled to paper over bitter primary wounds.

National money and star power meet a 93 percent favorite

Hyde-Smith remains the clear favorite at home. DDHQ’s state average leaves almost no daylight for Colom in the head-to-head forecast, even while Democrats nurse slim national hopes of retaking the upper chamber.

Trump, for his part, has been on a midterm blitz through red and purple states, including stops in places such as Texas, Oklahoma, and Ohio, aimed at keeping Republican control of Congress. The contrast is straightforward: one side fortifies its defenses where it already leads; the other airlifts a former president into a state that last elected a Democratic senator in the Reagan era.

Obama’s name still carries weight inside Democratic lanes, and Senate hopefuls elsewhere have adjusted old attacks on him when the politics required it, as seen when a Michigan Senate hopeful softened past Obama attacks under pressure.

Party discipline on the Democratic side is uneven in this cycle. Progressive primary winners have already tested leadership, with coverage of how Schumer’s grip on Senate Democrats slips as new nominees chart their own course.

Blue slips, old fights, and a familiar Obama playbook

The blue-slip episode is more than résumé filler. It shows Mississippi’s sitting senators used a standard tool to keep Colom off the federal bench when Biden put him forward. Now the same figure returns with Obama’s endorsement and a populist cost pitch.

Voters can weigh that record themselves. A prosecutor who fought local corruption, in the ad’s telling, is asking for a promotion after the state’s own senators twice rejected him for a lifetime judgeship.

Obama’s history with Senate-seat politics has drawn scrutiny before, including older FBI records detailing Obama and Emanuel talks in the Blagojevich Senate-seat case, a reminder that his orbit and upper-chamber maneuvering have long invited hard questions.

For now the operational facts are simple. Obama cut an ad. Colom is the Democratic nominee. Hyde-Smith holds a dominant position in a state that has not elected a Democratic senator in more than forty years. Gas and diesel prices are sharply higher than a year ago. And national Democrats are still searching for leverage in places where the local math runs against them.

Mississippi voters have heard the change pitch before. This time it arrives with a former president’s voice, a blocked judicial nominee, and a Republican incumbent who still owns the board.
