What the heck am I looking at?
We've created a map of the political campaign contributions from companies in the oil & gas industries to congressional representatives. This is a relationship map of the contribution network. That means that unlike a physical map, where points are positioned at a geographic location, the icons for the companies and representatives are placed so that they are that they are as close as possible to whomever they contribute to or receive contributions from.Another way to imagine it is like a molecule: the companies and representatives are like atoms, and the contributions are like atomic bonds. Or, one can think of it like the popular websites Facebook or MySpace, in which companies and politicians have become 'friends' by giving money.

Example: Contributions to Hillary Clinton's Senate campaign.
How does it work?
We wrote software to go through a database of contributions and pull out all the contributions from known oil company Political Action Committees or employees thereof. We only look at the contributions that went to the selected group of elected officials (House, Senate, etc.) while they were in office. Contributions that are below the specified minimum are discarded.Next, we check how much each company gave, and how much each representative received and exclude those that don't meet the minimum that has been set (under 'Filters'). We add up all the contributions and run this data through network visualization software to position the companies and politicians according to their ties. We also pull the identification numbers for the original FEC records so that it is possible to click through from the table view and see the exact FEC filing the data came from.
Where did you get the data?
Anybody who runs for federal office is required to file reports with the Federal Election Commission (FEC) giving the names and addresses of everyone who donates more than $250 to the campaign. This information is available free of charge from the FEC. We also purchased data from the non-profit Center for Responsive Politics that that group has painstakingly cleaned and categorized. We also used tools, data, and information from the following sources:- Center for Responsive Politics
- Categorized oil contributions and company names
- Assistance with data interpretation
- GovTrack.us
- Representative photos (courtesy of the Government Printing office)
- Information about who is in office when
- Sunlight Labs API.
- Some additional representative photos
- Information about current members of congress
- ID number conversion tables
- Zip code lookup
- Images of company logos were acquired from company websites without permission or authorization and may be under copyright of the respective companies. They are used here nominatively to refer to the companies and do not in any way indicate an endorsement or sponsorship of this project by any of these firms.
How recent is this data?
Most representatives are only required to file quarterly, so in some cases data may be several months old. There is some additional delay while the FEC and the Center for Responsive Politics process the data. The date of the most recent FEC data release that we are using is shown on the bottom of each page. You can view the date of each contribution by looking in the details of the table view.What do the settings under 'Filters' do?
To make our relationship maps easier to read, we've included filters that make it possible set what range of values should be shown. Adjusting these settings to lower values will include more of the corresponding elements in the relationship and table views. For example, setting the option to 'Show contribution in the top 75%' means that all the contributions except the smallest values will be included in the views. (The actual dollar values used for filtering are displayed under the title for the map)- The 'Show contributions' option refers to each individual contribution received by a representative, By decreasing the minimum contribution amount, you will expand the number of listed contributions.
- The 'Show politician' option filters out politicians based on total amount of money that the representative accepted from the Oil and Gas Industry in the given time period. By decreasing the minimum total, more representatives will appear in the relationship map or table.
- The 'Show companies' option filters out companies based on the total amount of money that each company gave to federal representatives in the given time period. If a company gave less than the stated minimum, their details will not be listed on the relationship map or table. By decreasing the minimum total, more companies will appear.
