The cook political report moved four Senate races toward Democrats this week, sharpening the view that control of the chamber is becoming more difficult for Republicans. The changes come as lawmakers return to Washington after a more than two-week recess, with the partial government shutdown still unresolved and pressure building inside the party.
The latest shift places North Carolina and Georgia into the Democratic column from “Toss Up” to “Lean Democrat, ” while Ohio moved from “Lean Republican” to a “Toss Up” and Nebraska shifted from “Solid Republican” to “Likely Republican. ” The moves signal that the Senate map is no longer giving Republicans the same advantage it once did, even in states that have recently leaned their way.
Cook Political Report shifts four races
In North Carolina, former Democratic Governor Roy Cooper has been leading Trump-backed Republican Matt Whatley, adding to the sense that the race is tightening against Republicans. The seat opened after GOP Senator Thom Tillis said last year that he would not run for reelection, following a clash with Trump over the so-called One Big Beautiful Bill Act.
In Georgia, Republicans are still locked in a heated primary to find a challenger to Democratic Sen. Jon Ossoff, whose campaign has been drawing in significant cash ahead of the general election. The GOP nominee there is not expected to be chosen until May 19, leaving Republicans with an unsettled path into the fall.
Ohio and Nebraska become more competitive
Ohio is emerging as one of the clearest warning signs for Republicans. Former Democratic Sen. Sherrod Brown, who lost his seat in 2024, is working to return to the Senate against Republican Sen. Jon Husted, who was appointed after Vice President JD Vance moved on from the seat.
Ohio backed Trump three times and by more than 11 points in 2024, but the race is now far tighter. The latest polling has Husted and Brown neck-and-neck, and the Senate Leadership Fund has already committed $79 million to the Ohio contest, more than it is spending in any other state.
Nebraska is also turning into a more competitive race for Republicans. Sen. Pete Ricketts faces Independent candidate Dan Osborn, a mechanic-turned-Senate candidate who nearly upset Sen. Deb Fischer in 2024 before the incumbent won by more than six points.
What the shift means for the Senate
Democrats need to flip four seats to take back the majority, and the new movement in the map makes that task look more plausible. The cook political report changes come as anger over Trump, the war he started, and persistent high prices continue to shape the political climate heading into the midterms.
Republicans once had a map that seemed to protect their majority, but the latest shifts suggest the fight is becoming more dangerous for them by the week. The cook political report will remain a key benchmark as both parties watch whether the current momentum holds, especially in the races that now look most volatile.
