has a Truth-o-Meter
PolitiFactGeorgia - In partnership with the Atlanta Journal-Constitution. From the AJC: To fact-check a claim, reporters first contact the speaker to verify the statement. Next, the research begins. Reporters consults a variety of sources, including industry and academic experts. This research can take hours or a few days or even longer, depending on the claim. Reporters then compile the research into story form and include a recommended Truth-O-Meter ruling. The fact check then moves on to a panel of veteran editors who debate the statement and the reporter's recommended Truth-O-Meter ruling. The panel votes on a final ruling; majority prevails.
Read several newspapers, in order to get different perspectives on the candidates and on the coverage.
Also, some newspapers endorse candidates; the Atlanta newspaper, the AJC, does not. Search for "editorial" or "editorial board".
