WASHINGTON, D.C. — Democrats need to net four Senate seats in the November 2026 elections to flip control of the U.S. Senate, where Republicans currently hold a 53-47 majority. To capture a majority, Democrats must flip at least two seats in states that Trump won by double digits in 2024.

Democrats have six Senate pickup opportunities in 2026. Sen. Susan Collins of Maine is the only Republican incumbent seeking re-election in a state that Trump lost in 2024. Former Governor Roy Cooper is the Democratic nominee in the North Carolina Senate race to replace retiring Republican Sen. Thom Tillis.

Former Sen. Sherrod Brown is seeking re-election in Ohio after losing by four points in 2024. Former Rep. Mary Peltola is running for Senate in Alaska after losing the state's at-large House seat by three points in 2024. State Rep. James Talarico is the Democratic nominee for Senate in Texas, while a June primary will determine the Democratic Senate candidate in Iowa.

Three Democratic-held Senate seats are potentially vulnerable in Georgia, Michigan and New Hampshire. Democrats have won Senate races in Georgia, Michigan and New Hampshire recently. Democrats carried Georgia, Michigan and New Hampshire in at least one presidential election during the Trump era.

North Carolina has voted for the Republican candidate in every presidential and Senate election of the Trump era.

In the 2018 midterm elections, Sens. Sherrod Brown of Ohio, Jon Tester of Montana and Joe Manchin of West Virginia won re-election despite Trump carrying their states by wide margins in the previous presidential election. In the same 2018 midterm elections, Democratic incumbents Claire McCaskill in Missouri, Joe Donnelly in Indiana and Heidi Heitkamp in North Dakota lost their races.
