GOP Super PACs Rush to Defend Mississippi Seat as Midterm Panic Deepens

Key points

• Senate Leadership Fund, the primary GOP super PAC for Senate races, reserved approximately $160,000 for Mississippi ads on Thursday, with additional spending expected. This follows a Democratic investment of roughly $1.2 million in the same race.
• The decision to fund Mississippi comes after months of hesitation. Senate Republicans had previously declined to allocate resources to the state, focusing instead on battles in Texas, Ohio, Iowa, and Alaska. However, internal polls now show Democratic challengers within the margin of error in multiple deep-red states.
• Democratic candidate Scott Colom, a 43-year-old district attorney, has attracted high-profile support from former President Barack Obama, former Vice President Kamala Harris, and Georgia Senator Raphael Warnock. Harris campaigned with Colom on Thursday, while all four Black Senate Democrats have recently visited the state to boost his bid.
• Incumbent Senator Cindy Hyde-Smith’s campaign maintains confidence in victory, citing her record on infrastructure and border security. However, her fundraising has been weak, and she has historically underperformed President Trump in Mississippi, winning her 2020 term by 10 points compared to Trump’s 16-point margin.
• Ad spending in the Mississippi Senate race is set to surge from less than $5 million in the first nine months of 2026 to nearly $8 million in October alone. Democrats currently outspend Republicans by approximately $5 million to $2.7 million in the state.

Background

This development follows earlier reports that Democrats were shifting strategy to target deep-red states, including a $1.2 million ad blitz in Mississippi announced on October 20. Prior to this, national Republican resources were heavily concentrated in swing states like Ohio and Iowa, where Senate Leadership Fund had reserved tens of millions of dollars. The current move indicates a strategic pivot to defend traditional strongholds as the midterm election approaches.

How outlets are covering it

CNN emphasizes the unprecedented nature of GOP spending in Mississippi, highlighting the anxiety within the Republican Party and the effectiveness of Colom’s viral campaign moments. Axios frames the situation as part of a broader 'panic' across the Republican Senate map, noting that internal polls show Democrats within striking distance in multiple deep-red states, including Kansas and South Carolina. Politico focuses on the timing of Democratic investment, with Representative Bennie Thompson criticizing the party for waiting too long to support Colom, while also noting that some GOP leaders, like Whip John Barrasso, remain optimistic about retaining the Senate majority despite the challenges.

Why it matters

The Mississippi race serves as a bellwether for the Republican Party’s ability to hold its Senate majority. If Democrats can flip a seat in a state Trump won by 23 points in 2024, it signals a significant shift in the political landscape. The outcome will also test the effectiveness of Democratic strategies to mobilize Black voters in the Deep South, potentially influencing future election strategies in similar states.

What to watch

Expect increased ad spending from both parties in the final weeks before the November 3 election. National figures from both parties are likely to visit Mississippi to campaign, with Democrats focusing on voter turnout in Black communities and Republicans emphasizing Hyde-Smith’s record. The race will also influence resource allocation in other deep-red states, such as Kansas and South Carolina, where similar vulnerabilities have emerged.
