Senate Leadership Fund Launches First Ad Against Rep. Pappas in New Hampshire Race

The ad's reliance on a six-year-old debate clip signals that outside Republican spending in the New Hampshire Senate race is shifting from biographical framing to contrast messaging ahead of November.

The Senate Leadership Fund, a super PAC aligned with Senate Republican leadership, released its first negative advertisement of the New Hampshire U.S. Senate general election on Wednesday, September 9, 2026, targeting Democratic candidate and incumbent Rep. Chris Pappas (D-NH-1), according to a report by the Washington Examiner.

The advertisement, titled "Chris Pappas Lied to Voters," centers on a video clip drawn from a 2020 U.S. House debate between Pappas and his then-Republican opponent, Matt Mowers. During that exchange, Mowers pressed Pappas on an alleged relationship with a former Amazon lobbyist. The specific nature of the claim and the full context of that debate exchange were not reproduced in full in the available source material.

The Senate Leadership Fund is registered with the Federal Election Commission as an independent expenditure-only committee. Its total spending in prior election cycles is a matter of public FEC record. Filings for the current 2026 cycle, including any media buy amounts associated with this specific ad placement in New Hampshire, would be disclosed in the committee's next FEC report. As of publication, the specific dollar figure of this initial New Hampshire ad buy is not confirmed in available public filings.

Pappas, a Democrat representing New Hampshire's First Congressional District since 2019, entered the Senate race following the retirement announcement of Sen. Jeanne Shaheen (D-NH), who had held the seat since 2009. The open seat has drawn national attention from both parties given New Hampshire's status as a competitive general-election state in recent cycles.

The Republican nominee in the race is former Governor Chris Sununu, who served four terms as New Hampshire's governor from 2017 to 2023. As TCT previously reported, Pappas and Sununu are set as the general election matchup after both secured their respective party nominations.

The Senate Leadership Fund's decision to open with a contrast advertisement rather than a purely positive or informational spot is consistent with standard outside-group strategy in competitive Senate races during the general election phase. The group spent more than $230 million in the 2022 cycle, according to FEC records compiled by the Center for Responsive Politics.

Pappas's campaign had not issued a formal on-record response to the advertisement as of the time of publication, according to available source material. Whether Pappas's campaign or aligned Democratic outside groups have made or plan to make independent expenditures in response is not confirmed in current public FEC filings.

The 2020 debate clip at the center of the ad involves an exchange that is now six years old. The specific lobbying relationship referenced by Mowers in that debate, and any documentation of it, would be traceable through Lobbying Disclosure Act filings submitted to the Office of the Clerk of the U.S. House of Representatives and the Senate Office of Public Records, which catalog registered lobbyists and their employer relationships by year.

New Hampshire holds one of a small number of true open Senate seats on the 2026 map, making it a priority target for both the Senate Leadership Fund on the Republican side and the Senate Majority PAC on the Democratic side. Neither committee's full New Hampshire advertising schedules for the fall general election period have been publicly disclosed as of this date.

Several facts remain unknown from available public records: the total dollar amount of the Senate Leadership Fund's initial New Hampshire ad buy, the specific stations or digital platforms where the advertisement is running, and the full text and sourcing of the underlying claim about the Amazon lobbyist relationship. FEC independent expenditure disclosures filed within 24 to 48 hours of a qualifying disbursement would contain the media placement figures. LDA filings at the congressional disclosure portal would identify whether the individual named in the 2020 debate was a registered lobbyist and, if so, which clients they represented during the relevant period.
