PACs › Biggest individual donors
Co-Founder, Andreessen Horowitz · LOS ALTOS, CA
Mostly Republicans (58%). What they gave is every gift committees filed with the FEC from Marc L. Andreessen this cycle, refunds taken off. A gift to a PAC counts toward the side its gifts to candidates and its ads helped, split when it helped both; a campaign or party counts wholly to its party. The traced figure is each group's share of money from them times what the group put into 2026 federal races, added up; it is worked out by proportion, not filed. Job and city are as they filed them with the FEC, public records. How the money is read. Something wrong, or a person filed two ways?
