After well-publicized issues with the reporting of results, Iowa's Democratic caucuses are a virtual tie, with Pete Buttigieg, the former mayor of South Bend, Ind., collecting 26.2% of estimated delegates and Vermont Sen. Bernie Sanders getting 26.1%.

The caucuses' State Delegate Equivalents determine the winner, but Iowa Democrats also released two other data points: raw vote totals from the first caucus alignment, and totals from the second and final alignment.
