Where each campaign's committee money came from

Each column is one candidate and each figure is that candidate's own money, taken over that candidate's own itemized total. Nothing here is added across candidates, and the two groupings below are never added to each other: the first is who the FEC says runs the giving committee, which covers every dollar, and the second is what interest a source says that committee advances, which is a claim MyRepTracker makes and covers only part of the money.

These candidates are compared in the table above but have no stored breakdown of where their committee money came from, so they are named here rather than shown as a column of zeroes.

Last-minute contributions reported before an election

Within 48 hours of receiving a contribution or loan of $1,000 or more in the days just before an election, a campaign must notify the FEC. These notices are provisional: the same money appears again in the regular report covering those days, so it is not added to the amounts above and is not compared as a measure. Candidates file them only while their own election is close, so an absence here says nothing about a campaign's fundraising.

Direct contributions are money the campaign received. Independent expenditures are spending by other organizations that is not coordinated with any campaign, and are never added to a candidate's receipts. Source: Federal Election Commission ↗.
