Mississippi Democrats choose in March 2026 between incumbent Bennie Thompson and challenger Evan Turnage.

Mississippi voters will choose in the March 2026 Democratic primary whether to reelect 78-year-old Rep. Bennie Thompson, a three-decade incumbent and former chair of the House Homeland Security Committee, or to support his 34-year-old challenger, antitrust lawyer Evan Turnage, who is backed by a movement for younger Democratic leadership. Thompson, who holds a significant financial advantage with over $1.5 million in campaign funds, is running on a platform of economic populism and regulation of Big Tech and artificial intelligence. Turnage has raised about $200,000 since December but has less than $40,000 remaining. The 2nd Congressional District, a majority-Black Democratic stronghold in a Republican-leaning state, is expected to favor the Democratic primary winner in the general election, with political analysts viewing Thompson’s deep roots and incumbency as major advantages.
