Lobbyists featured on Influence Explorer have registered with the Senate Office of Public Records. Lobbyists regularly make campaign contributions above the disclosure threshold of $200 to politicians which makes their names appear in Federal Election Commission records. Their names also show up on lobbying disclosure forms when they lobby on a specific issue or company. All of this information will show up on a lobbyist's profile page on Influence Explorer.

Some of this data may be out of date

State influence data from the National Institute on Money in State Politics changed in format and availability during the 2013-2014 election cycle. While we work to integrate their new style of data release, state-level campaign finance data for the 2014 cycle and beyond will be unavailable. We apologize for the inconvenience, but heartily recommend trying out their snazzy new site at FollowTheMoney.org!

Campaign Finance


The charts below display lobbyists' contributions to federal and state races. For federal races, only political contributions over $200 are included in these totals. This is because the Federal Election Commission only requires campaigns to itemize contributions that are more than $200. For state races, the threshhold for itemizing each contribution varies by state.

For more information, see our Campaign Finance Methodology page.
