Key points

• Chris Pappas defeated John E. Sununu in the New Hampshire U.S. Senate race, keeping the seat under Democratic control.
• The race was pivotal for determining the balance of power in the U.S. Senate during the 2026 midterms.
• Pappas will become the first openly gay male U.S. senator upon taking office.

Background

The race to replace three-term Democratic Senator Jeanne Shaheen was one of several key contests that could shift the Senate majority. In October 2026, Pappas held a seven-point polling lead and received endorsements from 57 Republicans and independents, including former Trump-endorsed nominee Don Bolduc, signaling dissatisfaction with the Trump agenda among moderate voters. Pappas prioritized cost-of-living issues over impeachment in his final campaign push. The 2026 midterms also featured a gubernatorial race between incumbent Kelly Ayotte and Democrat Cinde Warmington, along with critical down-ballot races for state legislative control.

How outlets are covering it

AP News emphasized the historical significance of Pappas’s victory, noting he will be the first openly gay male U.S. senator and highlighting the rarity of Republican congressional wins in New Hampshire since 2010. NBC News provided detailed demographic data, showing Pappas’s strong performance among college graduates (65% support) and younger voters (69% for 18-29 year-olds), while Sununu performed better among older voters and those without college degrees. New Hampshire Public Radio focused on the broader implications for state-level control, noting that while the Senate race was a national focal point, down-ballot races for the state House and Senate were critical for local policy, with Republicans holding significant structural advantages in district maps. InDepthNH.org reported on high voter turnout and smooth operations at polling places, with many voters citing economic concerns as their primary motivation.

Why it matters

Pappas’s victory maintains Democratic control of a key Senate seat, impacting the balance of power in the U.S. Senate. The race also highlighted the growing divide between national party strategies and local economic concerns, with Pappas’s focus on cost-of-living issues resonating with voters. The outcome underscores the importance of New Hampshire as a bellwether for Democratic strength in traditionally Republican-leaning regions. Additionally, the victory of the first openly gay male U.S. senator marks a historic milestone for LGBTQ+ representation in the Senate.

What to watch

Pappas will take office as a U.S. senator, focusing on economic issues and healthcare costs. The 2026 midterms will determine control of the state House and Senate in New Hampshire, with Republicans holding structural advantages in district maps. The outcome of down-ballot races will influence local policies on taxes, education, and public spending. The broader implications of the 2026 midterms will shape the balance of power in the U.S. Senate and Congress, with Democrats seeking to maintain control and Republicans aiming to regain ground.
