Candidate filings come from the Federal Election Commission and cover federal races only. Incumbent and challenger labels are the FEC’s own, as filed. Sitting members are matched to this seat by state and district, never by name — so a candidate listed here is not thereby identified as the office-holder. Data via the ElectedConnect API.
