Democrats’ prospects for reclaiming control of the House have gained momentum after a series of rating changes from the nonpartisan Cook Political Report, which shifted several competitive congressional races towards Democrats.

The updated outlook underscores what many election analysts see as a potentially challenging political environment for Republicans heading into the 2026 midterms. Democrats need only a handful of net gains to retake the chamber, and Cook’s latest adjustments suggest the battlefield now includes more competitive opportunities for Democrats.

According to Cook’s analysis, a growing number of Republican-held districts are now a bit more competitive, with many now classified as "Lean Republican" or "Likely Republican" on Thursday as opposed to "Solid Republican."

Democrats are attempting to retake the House and Senate in the upcoming November midterms, and the GOP holds a 218-212 majority in the House as of June 18. Democrats would need to pick up four seats to win control or three seats to tie.

Newsweek reached out to Republican House Speaker Mike Johnson's office via email on Thursday for comment.

What To Know

Recent polling has shown Democrats maintaining an advantage on the generic congressional ballot, while concerns about the economy and voters' approval of President Donald Trump have possibly created headwinds for Republican candidates. Historically, the president’s party often faces challenges in midterm elections.

Notably, Trump has landed some primary election-related wins in the House. Republican Congressman Thomas Massie of Kentucky was successfully primaried as Trump backed his competitor.

The Cook Political Report breaks races up into seven categories, from "solid Republican" to "solid Democrat." Some races as of Thursday are now in the "likely Republican" category, one position away from "solid Republican." The move to "lean Republican" also pushes some races closer to a "toss-up."

According to the new Cook analysis, the races impacted are Alabama District 2, which is now likely Republican; Iowa District 2, now lean Republican; Michigan District 4, now lean Republican; Minnesota District 1, now likely Republican; North Carolina District 11, now lean Republican; Ohio District 7 and South Carolina District 1, which are both now likely Republican.

Alabama U.S. House District 2

One of the biggest obstacles facing Democrats, however, is Alabama’s newly redrawn 2nd Congressional District, where Republican lawmakers reshaped the seat after a Supreme Court decision loosened constraints on partisan mapmaking.

The revised district no longer includes Mobile, the political base of current Democratic Representative Shomari Figures, Cook Political notes. The changes reduced the district's Black population share from roughly 49 percent to 40 percent.

Michigan U.S. House District 4

Michigan, a perennial presidential battleground, is emerging as another key House battleground in 2026. In the state's 4th Congressional District, Republican Representative Bill Huizenga enters the race as the incumbent, but demographic and political shifts around Grand Rapids have made the seat potentially more competitive, Cook notes.

Democrats point to improving performance in traditionally conservative areas and the candidacy of state Senator Sean McCann as evidence that the race could tighten, Cook adds. However, Huizenga's fundraising network and established profile may help him withstand what is expected to be one of Michigan's most closely watched congressional contests.

Iowa U.S. House District 2

Iowa's 2nd Congressional District has become a race to watch following Republican Representative Ashley Hinson's decision to run for the Senate, creating an open-seat contest.

While Republicans retain an advantage in the northeastern Iowa district, Democrats see an opportunity amid heightened enthusiasm driven by statewide races for governor and Senate, Cook says.

What's Next

While control of Congress remains far from settled, the latest ratings could provide Democrats with a slightly clearer path back to a House majority. Republicans still hold structural advantages in several districts and continue to benefit from recent redistricting gains in some states.

Nevertheless, with more than a year remaining before voters head to the polls, the Cook report suggests Democrats are entering the midterm cycle with some momentum.
