Republicans Target Democratic House Seats as Tax Cuts and Border Security Reshape the 2026 Midterm Battle

With control of Congress at stake, Republicans are challenging Democratic-held districts across five states, putting immigration enforcement, tax relief and economic affordability at the center of the November elections.

The Republican Party is expanding its campaign efforts into several Democratic-held congressional districts as the battle for control of the U.S. House of Representatives intensifies ahead of the November 3 midterm elections.

Despite mounting national concerns about inflation, energy prices and the war with Iran, Republican candidates are competing in districts where immigration enforcement, tax policy and changing congressional boundaries have created important political disagreements.

Among the contests receiving attention are congressional districts in New Hampshire, New York, Ohio, Nevada and New Mexico.

These campaigns illustrate a broader Republican effort to compete for Democratic-held seats while simultaneously defending the party's narrow majority in the House.

As of October 8, Republicans held 218 House seats compared with 214 for Democrats, with three vacancies.

All 435 House seats will be contested in November, making individual district campaigns important to the balance of power in Washington.

New Hampshire: Trump-Endorsed Republican Challenges Democratic Candidate

In New Hampshire's 1st Congressional District, Republican Anthony DiLorenzo is challenging Democrat Stefany Shaheen for an open House seat.

The district is currently represented by Democrat Chris Pappas, who is running for the U.S. Senate.

DiLorenzo, a businessman who operates automobile dealerships, has received Trump's endorsement and emphasized his support for a business-friendly approach to government.

Although he supports significant changes to immigration policy, DiLorenzo has also advocated immigration reforms intended to address business and workforce needs.

Shaheen, a former Portsmouth city councilor and daughter of retiring Democratic Sen. Jeanne Shaheen, has concentrated on health care affordability and opposition to tariffs that she argues have increased consumer costs.

The contest places competing economic priorities before voters in a district that has supported Democratic congressional candidates in recent elections.

New York: Republican Candidate Focuses on Immigration and Government Regulation

In New York's 4th Congressional District on Long Island, Republican Jeanine Driscoll is challenging Democratic Rep. Laura Gillen.

Driscoll, a local government official in Hempstead, has emphasized immigration enforcement and opposition to state and regional policies she describes as excessive government interference.

Gillen has stressed economic affordability and her willingness to cooperate with Republicans on selected legislative issues.

The district presents an interesting political contrast.

Although Gillen won her congressional seat in 2024, the district supported Trump much more strongly than it did in the 2020 presidential election.

Republican gubernatorial candidate Bruce Blakeman, who serves as Nassau County executive, is also running a statewide campaign that will appear on the same November ballot.

The overlapping contests bring immigration, taxation, housing expenses and state government policy into the congressional campaign.

Ohio: Redistricting Changes the Political Landscape

Ohio's 1st Congressional District is another important battleground.

Democratic Rep. Greg Landsman is seeking reelection against Republican Eric Conroy, a former Air Force veteran and CIA officer.

The congressional boundaries were redrawn ahead of the election, incorporating additional Republican-leaning territory.

The new map includes Clinton County and rural portions of western Hamilton County while reducing the district's share of some Democratic-friendly Cincinnati suburbs.

The boundary changes followed a broader Republican redistricting effort intended to improve the party's congressional position.

Conroy has emphasized his national security background, while Landsman has focused on household costs, including utility bills.

The contest demonstrates how redistricting can alter the electorate and force candidates to address the concerns of communities newly incorporated into their districts.

Nevada: Tax Relief for Working Americans Becomes a Campaign Issue

In Nevada's 3rd Congressional District, Republican Marty O'Donnell is challenging Democratic Rep. Susie Lee.

O'Donnell, known for his work composing music for video games, including the Halo franchise, has become part of the Republican campaign effort in a district with a significant hospitality and tourism workforce.

Republicans have highlighted tax relief for workers receiving tips and overtime pay, provisions contained in the major federal tax law signed by Trump in July 2025.

The legislation created temporary federal income-tax deductions for qualifying tips and overtime compensation, subject to statutory limits.

Those deductions do not eliminate every federal tax obligation associated with such income, and the relevant provisions are scheduled to expire after 2028 unless Congress extends them.

Republicans have promoted the provisions as evidence of their support for working Americans.

Democrats have criticized other aspects of the legislation, including its effects on health care programs and federal spending.

Lee has also emphasized the impact of higher gasoline prices and broader inflation on Nevada families.

The district supported Trump in the 2024 presidential election while simultaneously electing Lee to Congress, highlighting its history of split-ticket voting.

New Mexico: Border Security Takes Center Stage

In New Mexico's 2nd Congressional District, Republican Greg Cunningham is challenging Democratic Rep. Gabe Vasquez.

The district includes approximately 180 miles of the U.S.-Mexico border, making immigration policy and border enforcement especially relevant.

Cunningham, a Marine veteran and former undercover police officer, has emphasized stronger border security and law enforcement.

Vasquez, the son of Mexican immigrants, has built his political identity around representing a diverse border-region electorate while challenging elements of the Trump administration's immigration policies.

The district supported Trump in the 2024 presidential election but also reelected Vasquez to Congress.

That result underscores the importance of evaluating individual congressional candidates separately from presidential voting patterns.

Taxation, Immigration and Economic Pressure Shape the Final Weeks

The five contests demonstrate the different issues Republicans and Democrats are emphasizing in the final weeks of the campaign.

For Republicans, tax policy, immigration enforcement, public safety and government regulation remain prominent parts of their legislative agenda.

For Democrats, concerns about health care funding, rising prices, economic security and the administration's record are major campaign themes.

Neither party's national message necessarily determines how voters will respond in individual districts.

Local economic conditions, candidate records, changes to district boundaries and turnout will all contribute to the final results.

Both parties are committing substantial resources to congressional campaigns, with national organizations and outside groups investing in advertising and voter outreach.

The fundamental question for voters is what each candidate proposes to do in Congress about the issues affecting their communities.

From the suburbs of Long Island to the communities along the southern border, the 2026 House elections will determine which lawmakers hold legislative authority over immigration, federal taxation, government spending and domestic economic policy.

The answer will emerge when Americans cast their ballots on November 3.
