Aaron Bycoffe of data journalism website FiveThirtyEight has created a series of data visualizations illustrating the effect that candidate endorsements by representatives, senators, and governors have in presidential primaries in the United States. Bycoffe scored Republican and Democratic presidential candidates based on the number and type of endorsements received and graphed the progression of endorsements over time in comparison to candidates from previous election cycles. Bycoffe updates the visualizations regularly as candidates receive new endorsements.
