Republicans face high hurdles as they defend their razor-thin control of Congress in the 2026 midterm elections, but the Senate GOP campaign chair says he remains “incredibly optimistic” his party can not only hold but expand its current 53–47 majority.
Republicans are battling stiff political headwinds as the party in power in the nation’s capital traditionally loses seats in the midterms, and a rough political climate fueled by economic concerns amid persistent inflation and President Donald Trump‘s underwater approval ratings.
“There’s no doubt the climate has gotten more and more difficult by the day, it seems like at times,” National Republican Senatorial Committee (NRSC) Chair Sen. Tim Scott said in a recent Fox News Digital interview.
But he added, “The good news is we have a president who made promises, he’s been keeping those promises, and we have been able to recruit the highest quality candidates anyone could want in every single battleground state.”
WHAT THE SENATE REPUBLICAN CAMPAIGN CHIEF TOLD FOX NEWS
The NRSC chair told Fox News Digital in December 2025 that in the battle for the majority, “54 is clearly within our grasp right now, but with a little bit of luck, 55 is on our side.”
Asked again a week ago, Scott said, “I think we have a possibility of more than 53 seats.”
STRATEGY SESSION: TRUMP TEAM HUDDLES ON MIDTERM MESSAGING
Scott’s rival, Democratic Senatorial Campaign Committee (DSCC) Chair Sen. Kirsten Gillibrand told Fox News Digital in January that “President Trump is creating a toxic agenda that’s harming people.”
And Gillibrand emphasized she’s “optimistic that we have a shot to take back the majority.”
Here’s a look at the top 10 Senate seats that could flip in the midterms.
Longtime Republican Sen. Susan Collins is the only Republican senator running for re-election this year in a state that then-Vice President Kamala Harris carried in her 2024 presidential election defeat to Trump.
And Collins has seen a deterioration of her poll numbers among Mainers from her last re-election six years ago.
But Collins, who has long been a top target of the rival Democratic Senatorial Campaign Committee (DSCC) has proven impossible to beat, to date.
Complicating the Democrats’ push to flip the seat is a competitive primary between two-term Democratic Gov. Janet Mills, who has the tacit backing of longtime Senate Democratic Leader Chuck Schumer and the DSCC, and veteran and oyster farmer Graham Platner, who is running to the left of the governor and who is backed by progressive champion Sen. Bernie Sanders of Vermont.
Republicans are defending an open seat in the southeastern battleground state, with GOP Sen. Thom Tillis retiring at the end of 2026.
Democrats landed their top recruit when former two-term Gov. Roy Cooper launched a Senate campaign in summer 2025. Cooper enjoys tons of name ID in North Carolina and is 6–0 when running statewide races.
Republicans are rallying around former Republican National Committee (RNC) Chair Michael Whatley, who has the president’s backing.
The race is expected to be one of the most expensive and competitive Senate showdowns this year.
Democrats scored another major recruiting victory when former longtime Sen. Sherrod Brown announced he would challenge Republican Sen. Jon Husted.
A former lieutenant governor, Husted was appointed to the Senate a year ago after then-Sen. JD Vance stepped down to serve as vice president.
Ohio, once a premiere general election battleground, has turned red over the past decade, and Democrats view Brown as their only competitive candidate in the race to serve the final two years of Vance’s term.
Brown lost re-election in 2024 by roughly four points while Trump carried Ohio by 11 points.
Similar to North Carolina, the showdown is expected to be very expensive and competitive.
Democrats were given a big boost in the red-leaning state when former Rep. Mary Peltola announced in February that she would challenge GOP incumbent Sen. Dan Sullivan.
Peltola lost re-election 15 months ago in the at-large district that covers the entire state by three points, while Trump carried Alaska by 11 points.
Republicans are defending an open seat in Iowa, a onetime swing state that’s shifted to the right over the past decade.
But the GOP has rallied around Rep. Ashley Hinson, who is backed by Trump, in the race to succeed retiring Republican Sen. Joni Ernst.
Hinson, a former local TV news anchor who flipped a Democratic-held seat in 2020, is seen as a rising star in the party.
Democrats have a contested primary that includes state Rep. Josh Turek, a Paralympian, state Sen. Zach Wahls and military veteran Nathan Sage.
Longtime Republican Sen. John Cornyn of Texas is in the middle of a competitive and combustible GOP nomination runoff battle against state Attorney Gen. Ken Paxton.
Trump, to date, has stayed neutral in the runoff, which will be held in late May.
Cornyn enjoys the backing of Senate Majority Leader John Thune and the NRSC, which worries that the seat would be vulnerable if Paxton, who has plenty of political baggage, wins the primary.
The Democrats, who are eyeing the seat in the right-leaning state, nominated state Rep. James Talarico, a rising star in the party.
Republicans are optimistic they can flip a seat in the Great Lakes battleground, where Democratic Sen. Gary Peters is retiring.
The GOP, led by Trump, has coalesced around former Rep. Mike Rogers, who lost an extremely close Senate race in 2024 even as Trump won Michigan by one point.
The Democratic primary is a three-way race between center-left Rep. Haley Stevens, state Sen. Mallory McMorrow, a self-described “pragmatist,” and progressive physician Abdul El-Sayed, who is backed by Sanders.
The primary already has exposed divisions on the future of the state’s manufacturing sector and support for Israel, and the nominee won’t be decided until August.
Republicans view first-term Sen. Jon Ossoff as the most vulnerable Democratic senator seeking re-election in the midterms.
The aim was to paint Ossoff, the only Senate Democrat running for re-election in a state Trump won in 2024, as a far-left progressive.
But ousting Ossoff won’t be easy, in part because the senator’s robust fundraising has built a massive war chest.
And Republicans are in the middle of an ugly three-way between Reps. Mike Collins and Buddy Carter, and former University of Tennessee football coach Derek Dooley, who has the backing of term-limited popular, conservative Gov. Brian Kemp.
Trump has remained neutral, to date, ahead of the May primary.
Republicans are hoping to flip the long-held Democratic Senate seat in New England’s only swing state, thanks to the retirement of Sen. Jeanne Shaheen, the first woman in the nation’s history to be elected governor and senator.
While most Democrats are rallying around four-term Rep. Chris Pappas, there’s a spirited primary on the Republican side between two former senators seeking a return to Capitol Hill. Former Sen. John E. Sununu, an older brother to former Gov. Chris Sununu, has the backing of the president. But Trump’s first-term ambassador to New Zealand, former Sen. Scott Brown, remains in the race.
Republicans are trying to break their 16-year losing streak in U.S. Senate elections in the Granite State.
The retirement of Democratic Sen. Tina Smith is giving the GOP hopes they can flip the seat in the blue-leaning state.
And the NRSC landed what they say is a top-tier recruit in former NBC sports reporter turned conservative pundit and activist Michele Tafoya.
Tafoya is part of a crowded GOP field that also includes 2024 Senate nominee Royce White, a former NBA basketball player; retired U.S. Navy officer Tom Weiler, a 2022 GOP congressional nominee; former state Senator David Hann and former Navy SEAL Adam Schwarze.
Minnesota Lt. Gov. Peggy Flannagan, a progressive, is facing off against more moderate Democratic Rep. Angie Craig, who appears to have the backing of Senate Minority Leader Chuck Schumer, in the race for their party’s nomination.
