WASHINGTON (AP) --Joe Biden has won Arizona's Democratic presidential primary.
The state's top election official had declined to seek a delay because of the coronavirus, saying there was no certainty that putting off voting would help.
Most of the 1.2 million registered Arizona Democrats cast ballots early by mail, but about 300,000 could vote in person Tuesday.
According to figures obtained by The Associated Press, turnout among Democrats had already surpassed the 2016 election.
Over 480,000 votes had been cast by Tuesday morning.
Biden also won Illinois and Florida primaries Tuesday. Ohio canceled its election because of coronavirus fears.
