Endorsements are one of the ways voters learn who candidates are and what they stand for — especially in down-ballot races where little other information is available. Ballotpedia tracks endorsements from organizations we call Recognized Endorsement Contributors (RECs): groups ranging from labor unions and advocacy organizations to newspaper editorial boards that publicly support candidates and communicate those choices to voters. In the primaries on June 2, we tracked 463 endorsements from 46 RECs across five states: Iowa, Montana, New Jersey, New Mexico, and South Dakota.
Eleven organizations issued more than 10 endorsements each in these primary elections. The table below displays the organizations and their endorsee success rates. Candidates endorsed by these organizations won 88% of their races, lost 8%, and the remaining races were still too close to call.
