Political leanings: Democratic
2024 total spending: $391.2 million
Senate Majority PAC, formally known as SMP, is a super PAC that describes its “one mission” as helping Democrats “win Senate races.”
It’s headed by J.B. Poersch, a former executive director of the Democratic Senatorial Campaign Committee. Poersch was named the super PAC’s president in early 2017. Other senior staff include Amanda Ach, digital director, and Lauren French, communications director. Ach previously worked for the Democratic Congressional Campaign Committee, and French was recently a senior adviser at the State Department during the Biden administration.
As a super PAC, Senate Majority PAC is allowed to raise and spend unlimited amounts of money, but it must report expenditures and all donations of more than $200 to the Federal Election Commission. The group cannot make contributions to candidate committees and cannot coordinate independent expenditures with candidate campaigns.
In a July 10 press release, SMP announced that along with Majority Forward, an affiliated nonprofit group, it raised $147 million in the second quarter of 2026, “their best second-quarter fundraising ever.” The groups have now collected a combined $326 million since the beginning of the election cycle, and SMP had about $126 million in cash on hand at the end of June, the press release said.
Unlike SMP, which files quarterly financial reports with the FEC, Majority Forward, a 501(c)(4) organization, is only required to file an annual report with the IRS at the end of the group’s fiscal year. We don’t know who is donating to Majority Forward because the group is not required to disclose its donors. However, according to FEC data through March, Senate Majority PAC’s largest contributors include Majority Forward, the George Soros-funded Democracy PAC and retired media executive Fred Eychaner.
SMP previously announced that it would run eight-figure TV and digital ad campaigns in the fall supporting or opposing Senate candidates in Alaska, Georgia, Iowa, Maine, Michigan, New Hampshire, North Carolina and Ohio. We’ve already written about two of Majority Forward’s TV ads that attack the incumbent in Maine, Republican Sen. Susan Collins.
During the 2024 elections, SMP spent about $391.2 million and more than $325 million of that was contributed to other political committees, including WinSenate PAC, an affiliated super PAC that also worked to elect Democrats to the Senate.
