Here at OpenSecrets.org, we provide breakdowns of data reported by outside spending groups to the Federal Election Commission (see menu at left). We have a separate section devoted to dark money groups – politically active nonprofits that aren't required to publicly disclose their donors, unlike virtually every other organization spending money to affect the outcomes of federal elections. Through a dedicated project, we have dug up data on the donors of more than $1 billion – and counting – since 2008.
