Republicans began the 2026 midterm election cycle with the Senate map as one of their biggest advantages. It hasn’t turned out that way.

With less than two weeks until Election Day, President Donald Trump is defensively campaigning in GOP strongholds including South Carolina and Mississippi. Groups are pouring money into deep red states such as Texas. There are signs Republicans have largely given up on winning in places where they should have an edge, including Georgia and North Carolina.

Party insiders say this year’s “red wall” — a set of reliably Republican states that are necessary to ensure a majority — includes Iowa, Ohio and Alaska, which Trump won by double digits just two years ago.

Polling and early voting suggests momentum is with Democrats, who need to net four seats to win the chamber.

Whether the party is able to sustain that drive through Nov. 3 will determine whether they’re able to overcome the GOP’s geographic and fundraising advantages. Democratic strategists say it will still be a challenge to win the Senate since they will need to prevail in states Trump has carried handily.

“I’m of the belief that if the wave is high enough to breach the wall they’ve built with all this money and all these television ads, then you could have a Senate with 53 to 54 Democrats,” said Democratic strategist David Axelrod. “If the wave is smaller, Democrats could be struggling to get to 51.”Few anticipated the fight for the Senate would be contested on the ground it is today.

In early 2025, the only two contests Democrats saw as real pickup opportunities were North Carolina and Maine, according to a Democrat working on Senate races who declined to be named in order to discuss internal thinking. As the political environment deteriorated for Republicans, they added Ohio and Alaska to the list. And more recently Texas, Iowa and Kansas became additional prospects, the person said.

Trump has implored his most loyal supporters to act as if he is on the ballot, an appeal to lower propensity voters who have shown up in general elections to support him but not in off-year contests.

He has also offered a growing list of sweeteners, including promising to sending $5,000 checks to Americans if Republicans hold the House and Senate and a bailout package for farmers, who have been hard hit by his policies.

But his rallies have also veered into bizarre rhetoric at times, with Trump spewing profanity and slurs, criticizing the fashion sense of Ken Paxton, the Republican Texas Senate candidate, and waxing poetic about Ohio Senator Jon Husted’s physique.

And while he has projected confidence and argues that polls are often wrong, Trump has also at times seemed to acknowledge the position his party is in. At a rally in North Carolina, he appeared to concede that Democrat Roy Cooper was likely to defeat Republican Michael Whatley. “He’s going to become your senator and it’s crazy,” Trump said at one point.

White House spokesman Davis Ingle said that Trump had “created one of the most robust coalitions in political history with the MAGA movement, and the President understands how to communicate with them.”“President Trump is the unequivocal leader, best messenger, and unmatched motivator for the Republican Party, and he is committed to maintaining Republican majorities in Congress,” Ingle said in an emailed statement.

Polls show many of the races that will determine Senate control remain closely contested. While there are different factors in play in each state, voters’ low marks of Trump’s leadership as well as frustration over the cost of living and the war in Iran is weighing on all the candidates.

A recent New York Times poll showed just 36% of likely voters approve of Trump’s leadership, compared with 59% who disapprove. An overwhelming 75% of likely voters rate the country’s economic conditions as fair or poor and majorities thought Democrats would do better than Republicans handling issues including the economy, gas prices and foreign wars.

The Democratic strategist working on Senate contests said their party is benefiting from the political moment, but also from strong candidates who fit their states and can argue a case that goes beyond anti-Trump rhetoric.

Republicans are now counting on an enormous spending advantage to help them hold the line, including hundreds of millions from Elon Musk, Trump’s super political action committee and Republican committees.

A GOP consultant, who requested anonymity to speak candidly, said that Republicans are fighting to hold the red wall states, saying that they remain very close and arguing there is still a better than even chance to retain Senate control. Another state Republicans see as key to their chances is Maine, which Trump lost in 2024, but where incumbent Senator Susan Collins has long proved resilient in the face of Democratic challenges.

But the consultant said the GOP spending only goes so far in this climate and at some point there are diminishing returns. Additionally, Trump’s policies on the economy, immigration and the Middle East war are dragging Republicans down with voters.

Agricultural states such Iowa and Kansas have struggled with Trump’s tariffs and with diesel prices. States that do substantial trade with Canada, including Michigan, Alaska and Maine, have suffered from the president’s trade war with Ottawa.

And across the board, voters are upset about costs at the pump, the grocery store and the doctor’s office — and have said that Trump has paid more attention to building ballrooms than lowering prices. Trump has pointed to a solid job market, tax breaks on tips and overtime and refunds as proof the economy is stronger, but higher costs have eroded those gains for consumers.

Voter anger against political elites has also grown, as Americans voice frustration with corruption and what they see as self-dealing in Trump’s Washington.

“The daily deluge of new revelations of grift coming out of the White House is an enormous burden on Senate Republican candidates,” said Marc Short, a Republican strategist who worked in Trump’s first administration. “Giant holes have been forged in the firewall.”
