Crypto-backed super PAC Fairshake has begun a $30 million advertising and direct-mail campaign opposing former Democratic Sen. Sherrod Brown's attempt to return to the Senate from Ohio. The initiative, described by The New York Times as the industry's most aggressive midterm effort so far, began after the Senate failed on September 15 to advance the Digital Asset Market CLARITY Act in a 49-50 procedural vote, short of the 60 votes required. Fairshake previously spent about $40 million to $41 million targeting Brown in 2024, when Republican Bernie Moreno defeated him. Brown is now challenging Republican Sen. Jon Husted in Ohio. Fairshake said it would announce additional House and Senate spending, including support for candidates from both parties, while its general-election spending this year is expected to favor Republicans.
