The Data

The Data

Jefferson’s List has compiled publicly available data sets from reporting commissions across the country that were produced by campaigns required by law to provide itemized information on expenditures.

The data are then provided to the public by the governing body that oversees the election. In the United States, the Federal Elections Commission oversees all 536 federal races. Then each of the 50 states oversees their own legislative and statewide races. Finally, most counties and municipalities oversee their elections for local races such as mayors, commissions, coroners, registers, district attorney, etc.

Of the estimated $100 billion dollars spent in the political system over the last 20 years, Jefferson’s List has procured, collated, and released over $30 billion in transactions with more being added every day.
