DemDaily: The Endorsement Race
The endorsement of party leaders and elected officials has historically been a major predictor of success for candidates in Presidential primaries.
The early support of Governors, US Senators and Members of Congress are considered of particular value for their perceived influence with colleagues and, most importantly, their voting constituents.
Every candidate since 1980 who has led the endorsement race leading into the primary and caucuses has gone on to win their party's nomination - with the exception of the 2008 Obama/Clinton Democratic primary contest.
The 2016 Endorsement Tally
To-date, 318 of approximately 585 key elected office holders have endorsed. As tracked and weighted by the site FiveThirtyEight: 10 points for Governors, 5 points for US Senators and 1 point for US Reps.
The 2016 Presidential has already broken the mold on other traditional stats. We will see how it plays out!
