Money groups spent on their own, not through a campaign. Each ad is filed against the candidate it names, so money attacking an opponent shows on the opponent’s row. Open a candidate to see who spent it.
Each group that spent in this race is followed to where its own money came from, and what it spent is split by those shares: a group whose money was 60% one person's counts as 60% of its spending theirs. Of what traced, 38% to named individuals, 33% to organizations, 22% to tax-exempt organizations that need not name their donors, 7% not itemized in the filings.

By the state each donor wrote on the filing, across 6 states and territories. Donors who have given $200 or less this cycle are not itemized, so they cannot be placed on a map. The FEC’s grouping also counts joint-fundraising memo lines, so these rows can add up to more than the itemized total.

A further $4,000 came from donors whose answer names no employer (blank), so it is not ranked. Itemized gifts over $200, grouped by the words donors filed: not an industry classification, and a gift from an employee is not a gift from the employer. The FEC’s grouping also counts joint-fundraising memo lines, so these rows can add up to more than the itemized total. Gifts of $200 or less ($19,998) are not itemized, so no employer or occupation is filed for them.

Read for the 18 largest groups of 80, 96% of the $147.9M spent. Shares are of what each group received, not a record of which dollar went where; an organization that need not name its donors ends the trail; a person who gave by more than one route is counted once here. It shows who stood behind the money, not what it was for.
