Incumbent Rep. Michael Guest secured the Republican nomination unopposed in Mississippi's March 10 primary, capturing over 44,000 votes while Democrat Michael Chiaradio advanced with just 2,590 in his uncontested primary, teeing up the November 3 general election in this Solid Republican district with a Cook PVI of R+14. Trader consensus pricing Republicans above 90% stems from the district's entrenched GOP lean—Guest's prior wins of 71% in 2022 and 100% unopposed in 2024—coupled with his fundraising dominance ($942,000 cash on hand versus Chiaradio's $16,000 as of March 31) and absent intra-party challenges. Late-breaking scandals, health events for Guest, or a massive national Democratic midterm wave could theoretically challenge this, though historical base rates for safe seats favor continuity.
