FEC H4MA05084Gifts from the PACs’ FEC reports through Oct 14, 2026; lobbying from LDA filings through Q3 2026; votes from Voteview. Broad must-pass bills sort below narrow ones and do not set the money-bar scale.
Broad must-pass bills are left out of the figures above; 125 more PACs belong to organizations that lobbied only on those.
69 of Clark’s PACs have no federal lobbying on record or no organization Oathstar could match.
Filings lag, so recent gifts can take weeks to appear. Clark’s leadership PAC (Fair Shot PAC, Fight for a Democratic Majority PAC) is reported separately.
