Follow the Money in 2018
According to the Federal Election Commission (FEC): "An individual running for a seat in the Senate or the House of Representatives becomes a candidate when he or she raises or spends more than $5,000 in contributions or expenditures. House and Senate candidates must designate a campaign committee. This "authorized committee" takes in contributions and make(s) expenditures on behalf of the campaign." Campaign committees must file information on a quarterly basis with the FEC. The FEC then makes the information public on its website.
We will be tracking contribution totals for all of the candidates filing with the FEC on this page and posting a summary of their totals.
