The power struggle between progressive insurgents and the Democratic Party’s establishment rages on, but the establishment seems to be holding its ground in 2018, according to a new analysis.

When it comes to endorsements, FiveThirtyEight crunched the numbers this cycle to determine which influencers are having the most success winning primaries around the country. “The organization with the best endorsement record in Democratic primaries remains the Democratic Party itself,” FiveThirtyEight wrote. “Candidates who are on the Democratic Congressional Campaign Committee’s Red to Blue list or endorsed by the Democratic Senatorial Campaign Committee had a win rate of 95 percent (37 wins out of 39 endorsements). In races where a party-endorsed candidate ran against a progressive-group-endorsed candidate (excluding any races where a candidate was endorsed by both sides), the party-endorsed candidate won 89 percent of the time.” Our Revolution’s primary-win rate, by comparison, was 32 percent. Indivisible’s was higher, at 65 percent, but still much lower than the party committees’.
