PACs, super PACs and nonprofit committees have spent at least $283 million influencing the presidential race so far. Today we’re announcing changes to our FEC Itemizer database that will help you stay informed about who is spending that money and where they are spending it.

FEC Itemizer now shows more information about outside spending, not only in the presidential race but in House and Senate contests, too. It also provides more detail about committees’ activities, such as a page with summary totals for independent expenditures, along with subtotals for spending in each state.

You can also get a view of where a committee is making independent expenditures, with a color-coded map showing the levels of spending. In addition, each contest within a state (the presidential race has both state-level elections and a national one) has its own link that lists independent spending and the top-spending committees.

For the presidential race, we’ve also added pages that summarize and list independent expenditures that support or oppose a specific candidate (for example, those supporting Hillary Clinton or opposing Ted Cruz).

Along with these new features, we’ve also added:

• A page with super-PAC filings browsable by date.
• Summary totals for committee pages.
• The ability to browse a committee’s filings by a specific period; you can now quickly see whether what a committee raised in a reporting period was more or less than it has raised during the same period in previous years.
• The ability to see itemized records from electioneering communications filings that don’t specifically advocate the election or defeat of a candidate.
• A better summary of changes between an original filing and a later amendment, including a combined difference across all financial categories.
• Bulk downloads of itemized records for two committees: ActBlue and Bernie 2016. ActBlue, a Democratic conduit committee, routinely lists tens of thousands of donations and expenditures in each report, while Bernie 2016 also lists thousands of contribution records. Instead of displaying those records in the browser, FEC Itemizer now provides a zipped CSV file of them for each filing.
• Navigational “breadcrumbs” from every page so you know where you are.

With months to go before November’s election, we’re not done with FEC Itemizer, and we’d love to hear your suggestions for it and for the ProPublica Campaign Finance API.
