Top 50 Federally Focused Organizations

527 groups are tax-exempt organizations that engage in political activities, often through unlimited soft money contributions. Most 527s on this list are advocacy groups trying to influence federal elections through voter mobilization efforts and so-called issue ads that tout or criticize a candidate's record. 527s must report their contributors and expenditures to the IRS, unless they already file identical information at the state or local level. The figures below are taken from 527 group filings with the IRS.

For ease of identification, the 527 organization names used in this section are those of the connected organization, rather than the official name of the 527 account. For example, the "NEA Fund for Children and Public Education" is simply listed as "National Education Assn."
