DES MOINES, Iowa — The Iowa caucus counting fiasco is doing little to quell concerns that the 2020 Democratic nominating process won’t be “rigged” against Bernie Sanders, the way his supporters say it was in 2016.

The Iowa Democratic Party early Tuesday evening began releasing partial caucus results nearly 24 hours after the full batch was supposed to come out, helping set the narrative for the primary race going forward. The partial results showed Vermont Sen. Sanders narrowly behind former South Bend, Indiana, Mayor Pete Buttigieg in delegates, with 62% of precincts counted.
