2026 House Popular Vote Margin of Victory

Reps. Zach Nunn and Mariannette Miller-Meeks, Republicans in competitive Iowa House districts, joined Democrats and a handful of GOP colleagues on Tuesday in voting for a resolution to end U.S. military action against Iran without congressional authorization, reversing earlier votes against similar measures. It was the third such House vote, with a similar margin to prior attempts but a few more Republicans defecting, including retiring Rep. Nancy Mace and Reps. Tom Barrett, Warren Davidson, Brian Fitzpatrick and Thomas Massie. Rep. Ashley Hinson, running for Iowa's open Senate seat, voted against the measure, saying she wants a "decisive and immediate victory" instead.

The reversal comes amid political pressure ahead of the midterms, with the war remaining broadly unpopular and fuel and diesel prices rising as harvest season begins. Both Nunn and Miller-Meeks cited the need to bring troops home and end an open-ended conflict; 18 U.S. service members have died in the war, including two from Iowa. The White House says it has briefed Congress more than 30 times since February. Nunn had recently campaigned with Defense Secretary Pete Hegseth, prompting a Hatch Act complaint from former national security officials. Both lawmakers face competitive rematches in November, underscoring how the war's unpopularity is shaping battleground House races.

Control of the U.S. House this fall hinges on a map of roughly three dozen to 50 competitive races, with Democrats needing a net gain of just three seats to win the majority. Historically, the president's party has gained House seats in a midterm only twice since 1946, and Democrats are favored by generic-ballot polling and President Trump's low approval ratings, though analysts note Republican gerrymandering has made more Democratic-held seats competitive, offsetting some of that advantage. GOP leaders point to legislative wins and plan to tie Democrats to the party's left flank.

Key races include New York's 17th District (Mike Lawler vs. Cait Conley), Long Island's 3rd and 4th Districts, New Jersey's 7th, Ohio's 9th and 7th, California's 22nd and 48th, Arizona's 1st, and Virginia's 2nd. A House flip would make Hakeem Jeffries speaker and could block Trump's agenda while enabling investigative oversight.

Sen. Chris Murphy (D-Conn.) says the Pentagon blocked him from visiting Al Udeid Air Base in Qatar during a Congressional trip to the Middle East, calling it part of a "coordinated, deliberate campaign" by the Department of Defense to hide the true costs of the Iran War. Murphy, a member of the Senate Foreign Relations Committee, said he had never previously been denied access to a military facility despite more than a dozen trips to the region. The Pentagon countered that Murphy's office was told in advance that he would not receive support to access the base, citing travel restrictions on the region ordered by the secretary of war in March 2026.

Murphy, the first Senate Democrat to visit the region since the war began in late February, met with Saudi Crown Prince Mohammed bin Salman and Qatar's emir during the trip. He said he plans to draft legislation requiring the Pentagon to grant Congress access to overseas bases, warning the dispute reflects a broader clash between the administration and Congress over oversight of the war's consequences.

Rep. Shomari Figures, D-Mobile, introduced the Protecting American Beef Producers Act to nullify President Trump's proclamation allowing 300,000 metric tons of beef to be imported below market rate over a 90-day window. Trump announced the move in a surprise Truth Social post on Aug. 21, without naming which countries or companies were involved. The rollback is expected to take effect in September.

Figures' bill would require all imported beef and beef products to be subject to full tariffs, taxes, and fees, and would bar the president or any official from waiving or reducing such duties without explicit congressional approval or a declared emergency involving domestic beef supply. Figures has also pushed for a House Agriculture Committee hearing on the proclamation's impact on cattle producers and the beef supply chain. Several Republicans, including Sen. Katie Britt, along with major cattle and farm groups, have also opposed the tariff rollback, arguing it threatens American producers.

Homeland Security Investigations agents executed a search warrant Monday at Rep. Ilhan Omar's Washington, D.C. residence, seizing her phone, passport and computers, as part of a probe into whether she or her late father falsified her citizenship paperwork decades ago. The investigation could potentially lead to denaturalization proceedings against the congresswoman. Members of Minnesota's Somali community, including Minneapolis City Council Vice President Jamal Osman, denounced the raid as an abuse of power and an escalation of Trump's rhetoric against Omar and Somali Americans. Omar called the raid an "outrageous abuse of power" meant to intimidate a political opponent. Trump said the matter was up to the Department of Justice, calling Omar a "terrible person."

Missouri has become a flashpoint in the national battle over congressional redistricting ahead of the midterms. Last year, at President Trump's urging, the Republican-led state legislature redrew congressional boundaries mid-decade to weaken Democratic Rep. Emanuel Cleaver by extending his Kansas City-based district deep into rural, conservative territory.

A grassroots petition drive and subsequent legal challenges halted implementation of the new map. The Missouri Supreme Court ruled that any change to district lines must first be approved by voters in a public referendum, and the U.S. Supreme Court declined to intervene on Republicans' behalf. As a result, the original 2022 congressional map will appear on the November ballot, though Republicans are pursuing further legal avenues to overturn that outcome. The fight reflects broader nationwide efforts by both parties to reshape district lines mid-decade as they jockey for control of Congress.

Candidates running for Colorado's 1st Congressional District responded to a Denver Post questionnaire covering cost of living, energy policy, congressional oversight of the Trump administration, and immigration. Responses revealed sharp divides: some candidates called for Medicare for All, a moratorium on new fossil fuel leasing on federal lands, a path to citizenship for undocumented immigrants, and stronger congressional oversight of executive power, spending, and military actions. Others backed the Trump administration's agenda, supporting expanded oil and gas extraction on public lands, cooperation between local jurisdictions and federal immigration enforcement, and opposition to "sanctuary" policies.

A libertarian-leaning candidate called for auditing the Federal Reserve, ending corporate bailouts, returning land-use decisions to state control, and reclaiming congressional war powers, while criticizing both major parties for enabling executive overreach. A physician-candidate emphasized healthcare affordability, housing supply increases, protection of public lands for recreation and conservation, and a secure border paired with fast-tracked legal status for long-term residents. One candidate did not respond to the questionnaire.

U.S. Rep. Al Green, D-Houston, filed articles of impeachment against President Donald Trump for the eighth time, accusing him of operating ICE and Customs and Border Protection as "vicious, quota-driven, unaccountable paramilitary police forces." Green also sent Trump a letter citing deaths of people killed by immigration agents during his second term, including Houstonian Lorenzo Salgado Araujo, calling the matter one of "life and death" rather than partisan politics.

A White House spokesperson dismissed the effort as "garbage" contributing to rising assaults on law enforcement, crediting Trump's immigration policies with reducing violent crime. Green's previous seven impeachment attempts have all failed, with his closest vote, in December over Trump's remarks about executing lawmakers, losing 237-140. Green acknowledged long odds but said the resolution registers formal disapproval. He lost his primary for Texas' redrawn 18th District and will leave Congress in January after 21 years representing the state's 9th District.

Retiring Rep. Jared Golden (D-Maine), whose district borders Canada, broke with most Democrats to back President Trump's escalating trade fight with Canada, saying Canada "won't" fare well if it thinks it can do without US goods. Golden had previously supported Trump's tariffs on Canada earlier this year.

The dispute intensified after Trump imposed a 50% tariff on roughly $20 billion in Canadian goods, including beer, cheese, and electronics, following the collapse of bilateral trade talks. Canada responded with plans to match the tariffs dollar for dollar starting September 8, targeting hundreds of American product categories with duties ranging from 15% to 50%. The Trump administration has threatened further retaliation if Canada's countermeasures proceed.

Most of Maine's congressional delegation, including Sen. Susan Collins, has criticized the trade fight, warning of harm to the state's lobster industry. Trump has called Canada the most difficult trading partner he has dealt with and recently signed an order renaming Lake Ontario "Lake America." Canada remains the top US trading partner, though trade is proportionally more vital to its economy than to America's.

Rep. Jared Golden (D-Maine) has broken with most House Democrats to back President Trump's escalating tariff threats against Canada, warning that Canadian retaliation would ultimately backfire. The comments come as U.S.-Canada trade talks have broken down and Trump has threatened 50% tariffs on Canadian imports, prompting Prime Minister Mark Carney to pledge to match any U.S. penalties "dollar for dollar."

Golden, who represents a rural, working-class district bordering Canada, told the Portland Press Herald that if Canada believes it's better off without U.S. goods, "I wish them good luck," predicting it "won't go well for them" in the long run. Golden, a Marine veteran first elected in 2018, has previously supported protectionist trade measures and has announced he will not seek reelection, citing safety concerns for his family. His stance marks a notable split within the Democratic Party over the administration's trade conflict with Ottawa.
