With just 100 days remaining until the midterm elections, a new Decision Desk HQ forecast projects Democrats as the favorites to retake control of the House of Representatives, while Republicans remain slight favorites to hold the Senate in what is shaping up to be a closely contested election cycle.

Both parties are entering the final stretch facing significant political challenges that could reshape the landscape before voters head to the polls.

Republicans are grappling with renewed tensions involving Iran after hopes for a winding down of the conflict faded. The latest escalation has raised fears that the fighting could spread further, particularly as the Iran-backed Houthis threaten shipping through the Red Sea. The resulting increase in oil prices has added another layer of pressure to the Trump administration as economic concerns remain front and center for voters.

Democrats, meanwhile, are confronting growing internal divisions over the party’s future direction. Victories by democratic socialist and anti-establishment candidates in congressional primaries have fueled concerns among moderates that Republicans will portray the party as increasingly aligned with its progressive wing.

President Trump and Republican leaders have made that argument a central part of their campaign strategy, seeking to persuade voters that Democratic control of Congress would move the country too far to the left.

As a result, both parties enter the final 100 days with reasons for both optimism and concern.

“It’s a competitive situation in both the Senate and the House,” said Geoffrey Skelley, DDHQ’s chief elections analyst.

Democrats remain encouraged by the outlook in the House, where Republicans hold only a slim majority during a midterm election year—a political environment that has historically favored the party out of power. In the Senate, however, Democrats face a steeper climb, needing to flip several seats in states won by President Trump.

Decision Desk HQ currently projects Democrats winning a 225-210 House majority, giving them a 15-seat edge, while Republicans are forecast to maintain Senate control in a 50-50 chamber, with Vice President JD Vance casting any tie-breaking vote. As of late July, DDHQ gives Democrats a 60% chance of winning the House and Republicans a 60% chance of retaining the Senate.

The latest projection reflects a tightening House race compared to earlier this month, when the model suggested Democrats could gain as many as 25 seats.

Polling on the generic congressional ballot also indicates a narrowing advantage for Democrats.

According to DDHQ’s polling average, Democrats currently lead Republicans by four percentage points on the generic ballot. Recent surveys from YouGov/The Economist placed Democrats ahead by five points, while Morning Consult found a three-point advantage. Just a month ago, the Democratic lead averaged between six and seven points.

An Emerson College Polling survey offered a more favorable outlook for Democrats, giving them an 11-point lead on the generic ballot, although analysts caution it is too early to determine whether that represents a broader trend or simply an outlier.

Skelley said the Emerson findings “suggests a real range of opinions about what things are going to look like in the fall.”

Democrats hope dissatisfaction with President Trump and frustration over a Republican-controlled Congress will translate into electoral gains.

Much of that dissatisfaction has been driven by voter concerns about the economy, which continues to weigh on Trump’s approval ratings. Analysts expect economic issues to dominate the 2026 campaign, particularly as they intersect with developments in the conflict involving Iran.

“The big question is: will the Iranian conflict … will people being concerned about that ratcheting up, is that going to create reverberations in things like the generic ballot that signal ‘OK, Democrats’ advantage is growing again’?” Skelley said.

Earlier this year, Democrats’ lead on the generic ballot widened as tensions with Iran intensified and gasoline prices climbed. As energy costs eased during the spring, Republicans regained some ground in polling.

“The challenge for Republicans is the Iranian conflict is heating up again,” Skelley said, pointing to recent increases in gas prices as the conflict has escalated.

“This is politically very bad for the GOP. For them to try to make a case that Democrats are too extreme, it’s a lot easier to make that case if economic conditions are at least OK,” he said.

Polling conducted this month by The Economist/YouGov also highlighted voter skepticism about the conflict, with 57% saying the war was the wrong decision. While nearly 80% of self-identified MAGA Republicans supported the military campaign, only 51% of non-MAGA Republicans—a group representing roughly one-quarter of GOP respondents—expressed the same view.

Some Republican lawmakers have also voiced concern that Trump, who has dismissed affordability worries as a Democratic “hoax,” may be out of step with voters on economic issues.

“Given that President Trump was elected in part on the strength of how people viewed his handling of the economy during his first term … for polling to show sizable majorities disapproving of his handling of the economy or inflation or other things like that, it’s just very bad,” Skelley said.

Despite Republican concerns, Democrats face their own political hurdles.

Still searching for a clear national leader following their 2024 defeats and looking ahead to the 2028 presidential race, Democrats remain divided over whether the party should move toward the center or embrace its increasingly energized progressive base.

Candidates backed by the Democratic Socialists of America have scored several high-profile primary victories this cycle, while progressive challengers have defeated a number of longtime incumbents, signaling growing influence within the party.

President Trump has repeatedly attacked the democratic socialist movement, describing it as “communism” and “the biggest threat to our nation there is.”

Republicans “are going to be, from here until the fall, trying to sort of blanket the opposition with terms like ‘communists’ and ‘socialists,’” Skelley said.

One of the most closely watched races next month will take place in Michigan, where centrist Democratic Rep. Haley Stevens faces progressive challenger Abdul El-Sayed in a competitive Senate primary. The winner is expected to face presumed Republican nominee Mike Rogers in a race Cook Political Report rates as a toss-up, while DDHQ currently views it as leaning Democratic.

Some Democrats worry that if El-Sayed wins the Aug. 4 primary, Republicans could gain an advantage in the general election.

According to DDHQ, a Republican victory in Michigan would increase the party’s chances of holding the Senate to 86%.

“If Democrats are going to find a path to a majority, they cannot afford to lose Michigan,” Skelley said.

Even with Democrats positioned to make gains in the House, Skelley cautioned that the current political environment falls well short of the overwhelming Democratic momentum seen in 2018.

At this stage of the 2018 midterm campaign, Democrats held a seven- to eight-point lead on the generic congressional ballot—roughly double their current advantage, according to DDHQ.

With just over three months until Election Day, both parties are increasingly focused on a handful of closely contested races that are likely to determine control of Congress, making battleground states such as Michigan central to each side’s path to victory.
