But a huge increase in vote-by-mail ballots, driven in large part by the coronavirus pandemic, meant election officials were still counting ballots Friday.
The process led the AP to allocate 21 delegates to Biden late Friday, after it completed an analysis of votes released by election officials in the three states earlier in the evening.
Biden would have wrapped up the Democratic nomination much earlier, if not for the coronavirus pandemic 15 states, along with Guam and Puerto Rico, postponed their nominating contests due to the outbreak.
