WASHINGTON — After two years of struggling to slow down the Trump administration agenda under a Republican governing trifecta, Democrats are hoping to capture both chambers of Congress in the upcoming midterms.

All 435 House of Representatives seats are up for election, with 37 considered competitive, 21 of them toss-ups, by the Cook Political Report — a respected polling analysis site. Republicans currently hold a 218-214 edge over Democrats, with two seats vacant and one independent in the chamber.

To control the House, Democrats need a net gain of four seats.

Recent polls have shown Democrats creeping up on or surpassing their Republican opponents as President Donald Trump's approval rating hovers under 40%, which may offer an opening in unexpected places. But still, in a time when a more progressive wing has risen in popularity on the left, even some moderate Democrats are suffering from associations with the current administration.

Here is a look at five competitive races:

Ohio 7th: Miller vs. Poindexter

Incumbent Republican Max Miller, mired in controversy, will face union ironworker Brian Poindexter in a 7th Congressional District race that went from solidly Republican to a toss-up in the matter of weeks.

Miller, a second-term congressman, is facing a House Ethics Committee investigation after his ex-wife, Emily Moreno — daughter of Ohio Republican Sen. Bernie Moreno — accused Miller of extreme physical abuse, which he has denied.

Miller also faced accusations from former White House press secretary Stephanie Grisham that Miller had abused her during their relationship. An Ohio judge recently ordered both parties to remove social media posts about each other that were considered disparaging.

Poindexter, a relative unknown, has surged in the meantime. According to a Co/efficient poll last month, Poindexter was leading Miller by 14 points, with 86% of respondents claiming they were aware of allegations against Miller.

Poindexter has centered his campaign on strengthening unions, retaining healthcare benefits for retirees and injured workers and raising wages.

Miller has attacked his opponent for a 1998 arrest in which Poindexter, a teenager at the time, allegedly tried to swallow a rock of crack cocaine during a traffic stop. Miller also homed in on an instance of alleged assault at a baseball game in 2013 by Poindexter.

Texas 34th: Gonzalez vs. Flores

Incumbent Democrat Vicente Gonzalez Jr. is attempting to retain his seat against challenger Eric Flores, an Army veteran endorsed by Trump.

Elected in 2016, Gonzalez held the 15th Congressional District for three terms until 2021, when a Texas redistricting shift absorbed his McAllen home into the 34th district. He is currently serving his second term under a new map, which favors Republicans and has shed many of his Latino constituents.

Flores, a political newcomer, made his first national appearance at the Republican National Committee's midterm convention in Dallas, touting his commitment to border security and accusing Gonzalez of allowing migrants to make the community unsafe.

Immigration looms as an issue in the race. Gonzalez has introduced bills to prevent federal and state immigration enforcement officers from entering homes without an official warrant, and to force agents to wear clear identification. He has publicly criticized raids targeting hospitality, medical and construction workers.

Gonzalez has scored endorsements from several progressive organizations in the state, including LUPE Votes — a subsidiary of La Unión del Pueblo Entero.

In a Barbara Jordan Public Policy Research and Survey Center poll from August, Gonzalez was leading Flores, 45% to 42%, with 8% undecided.

North Carolina 1st: Davis vs. Buckhout

Incumbent Democrat Rep. Donald Davis will have to contend with a district that has grown more conservative to retain his seat against Republican challenger Laurie Buckhout.

North Carolina's 1st Congressional District was the state's only swing seat held by a Democrat before last year's redistricting, which made the area lean Republican. This will be a rematch of the 2024 race, which Davis won by less than 2 points, or around 6,000 total votes.

Cook Political Report ranked this race as leaning Republican, calling Davis "the most vulnerable House Democrat in the country."

It is unclear whether the gerrymandering effort will have been effective enough to make the district flip to Republican. Trump endorsed Buckhout in March and reiterated his support last week.

New York 17th: Lawler vs. Conley

New York Republican incumbent Rep. Mike Lawler is attempting to fend off a challenge from Democrat Cait Conley, a former White House director of counterterrorism on the National Security Council.

Cook Political Report rankings showed that early this year, the 17th Congressional District race went from likely Republican to a toss-up.

Pete Buttigieg went on the campaign trail last week with Conley to promote the candidate's bid to unseat Lawler.

"Cait is as serious as it gets about keeping our country safe," Buttigieg said on a rally stage in Tarrytown, "just like she is serious about bringing down the cost of housing, healthcare and energy."

Lawler has presented a bipartisan image in Congress, but has come under fire in his purple district for aligning himself with the Trump administration on several issues, including his support for the Iran war.

At the Republican National Committee's midterm convention, Lawler focused much of his speech on lambasting "socialist" Democrats and attempting to appeal to the more "common sense" wing of the opposition party.

"Radical socialists are winning Democratic primaries," he said. "They claim to be well-meaning, but there is nothing kind-hearted about protecting criminals at the expense of American families … nothing compassionate about prioritizing illegal immigrants."

Conley, however, has publicly refused to campaign with New York Mayor Zohran Mamdani or Rep. Alexandria Ocasio-Cortez — without condemning either figure — to avoid the open conflict between establishment figures and the more progressive wing of the party.

A July poll from co/efficient showed Lawler leading Conley 50% to 45%, with a nearly 3% margin of error.

Arizona 1st: Shah vs. Feely

A Democratic PAC plans to invest nearly $1 million to support Democrat state Rep. Amish Shah against Republican Jay Feely, a former NFL player with close ties to the president.

The 314 Action Fund — which seeks to elect Democrats with backgrounds in science, technology, engineering and mathematics — has made a big bet on the Democrat running in the 1st Congressional District, Arizona's wealthiest, according to the Arizona Mirror.

Subsequent ads have brought attention to Feely's close association with Trump and his recent attendance at the Republican National Committee's midterm convention in Dallas. Trump won the state by five points in 2024.

Elon Musk has also figured in this race, with his America PAC giving $24,000 to Republican candidates Feely in the 1st District and Juan Ciscomani in the 6th District, according to the Copper Courier.

The Cook Political Report called the 1st District "one of the most competitive … in the country."
