Democrats Gain Ground as Midterm Polls Put Congress in Play

Democrats are gaining momentum in the contest for control of the US Congress, with national polling showing a nine-percentage-point advantage over Republicans one week before the November 3, 2026, midterm elections. According to polling data compiled by Yahoo, the party is positioned to challenge Republican majorities in both chambers during President Donald Trump's second term.

The Democratic lead in the generic congressional ballot has widened over the past month, according to Yahoo's October 27 analysis. Democrats need a net gain of three seats to secure the House majority and four seats to take control of the Senate, where Republicans currently hold a 53-45 advantage over Democratic senators and two independents who caucus with them.

The national polling measure, commonly known as the "generic ballot," asks voters which party's congressional candidate they would support if an election were held that day. Although it does not account for the distinct dynamics of individual races, historical results show that the measure can indicate broader electoral shifts.

In 2018, Democrats held a 7.6-point average lead at a comparable stage before gaining 41 House seats under Trump's first administration. In 2022, Republicans led by three points before gaining nine seats and taking control of the House. Earlier midterm elections also favored the opposition party: Republicans gained 13 House seats in 2014 and 63 in 2010.

Democrats' current advantage comes as Republican-led states across the South have redrawn congressional districts to benefit their party, according to Yahoo. Nevertheless, Democrats need only three additional seats to overcome the House's narrow Republican advantage.

House Speaker Mike Johnson, a Louisiana Republican, is defending the party's legislative record, including the Working Families Tax Cuts Act, previously known as Trump's "One, Big Beautiful Bill." Johnson told CBS that Republicans were delivering economic improvements.

"We are bringing down the cost of living. We are providing more jobs and opportunity for more people. The facts show it and the records show it," Johnson said.

According to ABC News on October 27, Republicans effectively begin the election with a 220-215 advantage over Democrats when accounting for two vacancies. The House has 435 seats, with Republicans holding 218 seats and independent Rep. Kevin Kiley generally supporting Johnson.

Democrats hold 214 seats, while two vacancies followed the April resignations of former Republican Rep. Tony Gonzales of Texas and former Democratic Rep. Sheila Cherfilus-McCormick of Florida.

House Minority Leader Hakeem Jeffries, a Brooklyn Democrat, is campaigning on affordability and anti-corruption issues while seeking to become the first Black speaker in US history. He said voters were dissatisfied with the current administration and expressed confidence in his party's prospects.

"The American people are fed up," Jeffries told reporters this month, adding that Democrats are "on track" to win the House majority.

The Senate presents a more complicated map because individual state contests depend on local political conditions and candidate profiles. According to Yahoo's October 27 analysis, Democratic leads in Michigan, Georgia and New Hampshire have strengthened, while Republican-held seats in Iowa, Kansas, Nebraska and South Carolina have become more competitive.

In Ohio, Democratic former senator Sherrod Brown has led Republican incumbent Jon Husted by two to six percentage points in nearly every poll conducted since early October, although a recent Echelon Insights survey found the race tied. In New Hampshire, Democratic Rep. Chris Pappas has established an average seven-point lead over Republican John E.

Sununu in the race to succeed retiring Democratic Sen. Jeanne Shaheen.

Nebraska's Senate contest also warrants attention. Republican incumbent Pete Ricketts faces independent Dan Osborn, a veteran and former union leader supported by Democrats. Yahoo reported that recent nonpartisan polling suggested a competitive race, while two surveys affiliated with Osborn showed the candidates exchanging narrow leads.

Separately, NBC News published its Senate battleground polling overview on October 21, highlighting the importance of competitive races as Republicans seek to preserve their majority. ABC News reported that 35 Senate seats are on the November ballot, including 13 Democratic-held seats and 22 Republican-held seats.

Republicans can lose three Senate seats and retain control if the chamber becomes evenly divided, because Vice President JD Vance can cast a tie-breaking vote. Democrats must gain four seats to reach a majority without relying on that mechanism. Early voting is underway in multiple states, and Election Day is scheduled for November 3.
