Despite a map that had been expected to be unfavorable for Democrats, polling has shown a surge for the party in recent months.
As the U.S. primary season continues full steam ahead, some of the most critical 2026 Senate matchups have already been set.
From the Southeast to New England and the Rust Belt, races are taking form that will determine the makeup of the Senate in 2027 and beyond.
Despite a map that had been expected to be unfavorable for Democrats—going through states like Texas, North Carolina, Nebraska, Iowa, Ohio, and Alaska, among others—polling has shown a surge for the party in recent months, including in states that had previously been seen as relatively safe Republican holds.
Here’s the state of some of the cycle’s most important Senate races.
| Georgia | Iowa |
| North Carolina | Nebraska |
| Maine | Texas |
| Michigan | Alaska |
| Ohio |
Georgia
In Georgia, Republicans are again seeking to flip one of the state’s two Democratic seats, which have remained firmly under Democratic control since 2020.
Republicans selected Rep. Mike Collins (R-Ga.) to take on Ossoff.
Polls taken in the state so far have shown that Ossoff is favored to hold the seat, leading Collins in every poll taken so far, with the exception of a September 2025 poll by Quantus Insights, which found that Ossoff and Collins were tied in the race.
In 2024, President Donald Trump won Georgia by around 2.2 percent—one of the Republicans’ lowest margins of victory in the Peach State in decades.
That victory came amid high rural turnout, alongside strong margins for the president in the critical Atlanta-area suburbs, which were ultimately able to offset Democrats’ baked-in advantage with Atlanta metropolitan voters.
However, the state has been trending blue for years, and the 2026 contest represents a crucial test of Republicans’ continued viability in the state’s Senate elections.
North Carolina
In North Carolina, former Republican National Committee Chairman Michael Whatley is set to take on former Gov. Roy Cooper in one of the 2026 cycle’s most crucial matchups.
The two are vying to replace outgoing Sen. Thom Tillis (R-N.C.)—an outspoken critic of the Trump administration who announced last year that he wouldn’t seek reelection—after locking down their parties’ nominations on March 3.
While Republicans have held an advantage in the battleground state for nearly two decades—last sending a Democrat to the Senate amid the 2008 blue wave that coincided with President Barack Obama’s election—polls have shown that Cooper is in a favorable position.
Cooper, a popular former governor, has led Whatley by at least seven points in every poll taken in the state since February.
Two polls taken in March—including a poll by Catawba College and a poll by Nexus/Strategic Partners Solutions—found Cooper leading by more than 12 percent.
While polling paints a rough picture for Republicans, the state remains a critical target for both parties in the 2026 cycle.
