Independent spending filed on Iowa's races, by whether the committee is also spending in other states this cycle. A filing records where a group spends, not where its donors live, so this is a measure of reach, never of who paid for it.

Who is spending on Iowa

The groups spending independently on Iowa's races, by what they have filed. Open a row to see how the money was spent, supporting or opposing each party, and the interest behind the committee.
