Michigan Senate

Mike Rogers (R) vs Mallory McMorrow (D) vs Abdul El-Sayed (D) vs Haley Stevens (D)

Current: Gary Peters (D)

Michigan is one of two Democratic-held Senate seats in states Donald Trump won in 2024, making it critical for Republican flip opportunities and Democratic defense in a midterm environment favorable to the party out of power.

North Carolina Senate

Shaunesi Deberry (I) vs Shannon Bray (L) vs Brian McGinnis (G) vs Michael Whatley (R) vs Roy Cooper (D)

Current: Thom Tillis (R)

North Carolina is a must-win for Democrats to have any realistic path to regaining the Senate majority. With Republicans currently holding a 53-47 advantage, this open seat represents a critical battleground that will significantly influence overall chamber control.

Maine Senate

Susan Collins (R) vs David Costello (D) vs Graham Platner (D) vs Janet Mills (D)

Current: Susan Collins (R)

Maine is Democrats' clearest offensive pickup opportunity in 2026 and essential to retaking Senate control. As the only Republican-held seat in a Kamala Harris-won state, flipping Collins' seat is viewed as virtually necessary for Democrats to reach the 51 votes needed for majority control.

Ohio special

Stephen Faris (I) vs Gregory Levy (I) vs Bill Redpath (L) vs Ron Kincaid (D) vs Sherrod Brown (D) vs Jon Husted (R)

Current: Jon Husted (R)

This special election is critical for Senate control. Republicans currently hold 53-45 majority and need to retain this seat in a swing-trending state to maintain their advantage against Democratic gains elsewhere.

Georgia Senate

Derek Dooley (R) vs Mike Collins (R) vs Buddy Carter (R) vs Jon Ossoff (D)

Current: Jon Ossoff (D)

Georgia is one of only two Democratic-held Senate seats in states Trump won in 2024. This race is critical for Republicans seeking to expand their majority and Democrats defending against losses.

Tennessee Senate

David Sutman Jr. (I) vs Kevin Lee McCants (D) vs Diana Onyejiaka (D) vs Civil Miller-Watkins (D) vs Maria Brewer (D) vs Marquita Bradshaw (D) vs Bill Hagerty (R)

Current: Bill Hagerty (R)

Tennessee is a solid Republican state where Democrats have not won a Senate election since 1990. Holding this seat is crucial for Republicans to maintain Senate control.

New Hampshire Senate

Matt Giovonizzi (I) vs Charlie Hough (R) vs Tejasinha Sivalingam (R) vs Karishma Manzur (D) vs Scott Brown (R) vs John E. Sununu (R) vs Chris Pappas (D)

Current: Jeanne Shaheen (D)

This open seat in a slightly blue state is crucial for Senate control. With New Hampshire backing Democrats in federal elections but Republicans controlling state government, the race could determine narrow Senate majorities.

Alaska Senate

Richard Grayson (I) vs Dustin Darden (R) vs Mary Peltola (D) vs Dan Sullivan (R)

Current: Dan Sullivan (R)

Alaska is one of Democrats' few credible targets to flip a Republican Senate seat. Flipping Alaska along with Ohio and other seats is critical to Democrats' path to taking back Senate control.

Texas Senate

James Talarico (D) vs Ken Paxton (R) vs John Cornyn (R)

Current: John Cornyn (R)

Texas holds significant strategic value despite being reliably Republican. Democratic success would be historic—the party hasn't won statewide since 1994. With negative approval ratings for both top Republican candidates, Democrats see a genuine opportunity if the political environment shifts.

Nebraska Senate

Dan Osborn (I) vs Pete Ricketts (R)

Current: Pete Ricketts (R)

Control of Senate majority. A Ricketts win solidifies Republican hold; Osborn victory would flip seat to Independent and potentially swing narrow Republican advantage.

Minnesota Senate

Marisa Simonetti (I) vs Royce White (R) vs Billy Nord (D) vs Melisa López Franzen (D) vs Angie Craig (D) vs Peggy Flanagan (D)

Current: Tina Smith (D)

Control of the U.S. Senate depends on Democrats holding this open Minnesota seat; losing here would significantly damage Democratic hopes of winning back the chamber.

Iowa Senate

Thomas Laehn (L) vs Zach Wahls (D) vs Josh Turek (D) vs Jim Carlin (R) vs Ashley Hinson (R)

Current: Joni Ernst (R)

This open seat contest could be critical for Senate control. Republicans need to hold the seat given their narrow majority, while Democrats view this as a long-shot opportunity in a red state.

Idaho Senate

Natalie Fleming (I) vs David Roth (D) vs Todd Achilles (I) vs Jim Risch (R)

Current: Jim Risch (R)

This race has potential to shift Senate control if Todd Achilles (Independent) gains traction, similar to Nebraska 2024. However, Idaho's Republican dominance since 1981 and Risch's strong fundraising advantage make Democratic takeover unlikely.
