President Donald Trump and congressional Republicans are facing another warning sign ahead of the 2026 midterm elections as several closely watched races move in Democrats’ direction.
Larry Sabato’s Crystal Ball, the University of Virginia Center for Politics election forecasting operation, has shifted a series of Senate, House and governor’s races toward Democrats as analysts reassess the national political environment.
The changes do not mean the elections have been decided. But with control of Congress at stake, Republicans are facing increasingly competitive contests in several states that could play an important role in determining the balance of power in Washington.
Major Senate Races Move Toward Democrats
One of the most significant developments involves the battle for the U.S. Senate.
The Iowa Senate race moved from “Leans Republican” to “Toss-up,” signaling that analysts now see the contest as highly competitive.
Kansas also moved from “Likely Republican” to “Leans Republican.”
Meanwhile, Michigan shifted from “Toss-up” to “Leans Democratic,” giving Democrats a stronger rating in one of the most closely watched Senate contests of the election cycle.
The changes come as Republicans fight to maintain their Senate majority while Democrats attempt to capture enough seats to take control of the chamber.
Michigan remains a particularly important battleground.
Democrat Abdul El-Sayed is running against former Republican Rep. Mike Rogers in the race. Crystal Ball analyst Kyle Kondik has suggested that El-Sayed could perform differently than another Democratic candidate might have in Michigan, but the forecasting group nevertheless currently places the contest in the Democratic-leaning category.
Iowa Becomes a Major Senate Battleground
The move in Iowa could be especially concerning for Republicans because the state has generally favored the GOP in recent statewide federal elections.
A race that previously carried a Republican advantage is now being classified as a toss-up by Sabato’s Crystal Ball.
That does not necessarily indicate which candidate will win. Election ratings can change rapidly as polling, campaign spending, voter turnout expectations and national political conditions evolve.
Still, the change places Iowa firmly among the Senate races receiving increased national attention.
Republicans Face Trouble in Governor’s Races
The warning signs extend beyond Congress.
Sabato’s Crystal Ball also shifted two major gubernatorial contests from “Leans Republican” to “Toss-up.”
One is Nevada, where Republican Gov. Joe Lombardo is seeking reelection.
The other is Ohio, where Republican Vivek Ramaswamy is running against Democrat Amy Acton to succeed Republican Gov. Mike DeWine.
Both states are expected to receive significant attention as Republicans seek to retain control of their governor’s offices.
There was also movement in two of the nation’s largest Republican-led states.
The Texas and Florida governor’s races were downgraded from “Likely Republican” to “Leans Republican.”
Republicans remain favored under the Crystal Ball ratings in both states, but the new classifications indicate that the forecasting organization views the races as more competitive than before.
House Republicans Also See Warning Signs
Republicans received additional concerning news in the battle for control of the House of Representatives.
Several congressional races shifted toward Democrats, including contests involving Republican Reps. María Elvira Salazar of Florida and Mariannette Miller-Meeks of Iowa.
The race between Republican Alex Mealer and Democrat Leticia Gutierrez in Texas’ redrawn 9th Congressional District also moved in Democrats’ direction.
Sabato’s Crystal Ball still gives Republicans the stronger rating in some of those races, but Iowa’s contest involving Miller-Meeks has become particularly notable.
Democrat Christina Bohannan is attempting to unseat Miller-Meeks in a race that could have implications for the narrow fight over House control.
Salazar’s Immigration Dispute Draws Attention
Salazar has also attracted national attention over immigration policy.
The Florida Republican recently released a campaign advertisement criticizing aspects of the Trump administration’s immigration enforcement approach.
She later said Trump had been receptive to concerns she raised about Hispanic voters.
Trump, meanwhile, has continued to support Salazar and has maintained his endorsement of her campaign.
The episode illustrates one challenge some Republican candidates face as they campaign in politically diverse districts while also maintaining relationships with the Trump administration.
National Political Environment Raises GOP Concerns
Crystal Ball analysts have pointed to the broader national environment as an important reason for the latest rating changes.
The organization has made multiple adjustments toward Democrats during the 2026 election cycle as it evaluates individual races and the national political climate. Recent Crystal Ball analysis has also described the House battlefield as increasingly challenging for Republicans.
That matters because Republicans do not have a large margin for error.
A relatively small number of competitive districts could ultimately determine which party controls the House in 2027.
Likewise, a handful of Senate races could decide whether Republicans retain their majority or Democrats take control.
Another Forecast Shows a Close Fight for Congress
Decision Desk HQ is also showing a difficult national landscape for Republicans.
As of September 22, its 2026 election model gives Democrats a 71% modeled probability of winning the House and Republicans a 29% probability.
The Senate is considerably closer. The same model gives Democrats 53% and Republicans 47% probabilities of controlling the chamber.
Those numbers are projections generated by a forecasting model and should not be confused with polling results or actual election outcomes. They can change considerably before Election Day.
The trend has moved since Decision Desk HQ launched its forecast in July.
At that time, the organization gave Democrats a 62% probability of winning the House while Republicans had a 57% probability of retaining the Senate.
Decision Desk HQ said the national congressional ballot and Trump’s job-approval numbers were among the factors influencing its initial model.
Why the 2026 Midterms Matter for Trump
The stakes are particularly high for President Trump.
Control of Congress could have a major impact on the final two years of his current term.
A Republican Congress would generally give the administration more opportunities to pursue legislation on taxes, immigration, federal spending and other priorities.
If Democrats gain control of one or both chambers, the legislative environment would change significantly. Committee leadership, congressional investigations and the ability to move major legislation could all be affected.
That makes the House and Senate races important not only for individual candidates but also for the future of Trump’s agenda in Washington.
Republicans Still Have Time to Change the Political Landscape
Despite the recent shifts, the 2026 midterm elections remain unsettled.
Political forecasting ratings are snapshots based on current conditions rather than guarantees about what voters will ultimately decide.
Campaign advertising, debates, economic developments, turnout operations, polling changes and unexpected national or international events could all alter individual races before voters cast their ballots.
Republicans still hold advantages in a number of contests, while Democrats face difficult races of their own.
But the latest changes provide another indication that several races Republicans once viewed more comfortably are becoming more competitive.
With the November 3 midterm elections approaching, both parties are likely to focus enormous resources on the relatively small group of Senate seats, governor’s races and congressional districts that could determine who controls Washington.
For Trump and the GOP, the newest ratings provide a clear signal that the battle for Congress is entering a crucial stage — and that Republicans cannot assume their current majorities are secure.
