The final results of Monday’s Democratic Iowa caucuses remain unknown, with 71% of precincts reporting the final tallies of the first 2020 presidential contest. Senator Bernie Sanders is leading in the popular vote, while former South Bend Mayor Pete Buttigieg has a narrow lead of 26.8% of precincts — the state delegate equivalent traditionally used to determine the winner — followed by Sanders with 25.2%. Sanders won the popular vote in both the first and second rounds of voting, followed by Buttigieg and Senator Elizabeth Warren. Former Vice President Joe Biden placed fourth, followed by Senator Amy Klobuchar. It is unclear when full results will be released and how the reporting problems will impact the Democratic race. Democratic officials cited problems with a newly created app built by a firm called Shadow that was supposed to help precincts report results. The Democratic Party in Nevada was also planning to use the app during its upcoming caucuses but abandoned that plan on Tuesday. We speak with Lee Fang, a reporter with The Intercept.
