Democrats choose their party’s eventual White House nominee based on national convention delegates, and the state delegates are used to determine those totals in Iowa. The Associated Press will declare a winner in Iowa based on the number of state delegates each candidate wins. This is the first time the party has made public the first and final alignment results.
