See [[Defend the Vote]]. ## Open questions - Its own receipts for the 2026 cycle, which its reports disclose directly. - How much of its money reaches it from [[Majority Forward]], whose own donors are not on the federal record. ## See Also - [[Majority Forward]] · [[WinSenate]] · [[Defend the Vote]] - [[Super PACs]] · [[Independent Expenditure]] · [[Dark Money]] · [[Organizations Hub]]
