As a two-term vice president and 36-year senator, it’s not particularly surprising Joe Biden leads his 2020 Democratic primary rivals in endorsements from other officeholders. But less than six months out from the first nominating contest votes, in the Iowa caucuses, it’s unclear how much the endorsements will help.

Fivethirtyeight.com’s endorsement tracker shows Biden leading his Democratic primary opponents with a score of 110 points in the political endorsement contest, which is calculated by the number and quality of endorsements from current and former party leaders. The system weights endorsements by who is offering them, with vouchsafes from former presidents, vice presidents, and national party leaders worth a high of 10 points, to 1 point on the low end for a DNC committee member.
