Joe Biden won the Florida, Illinois and Arizona primaries on Tuesday, moving closer to the Democratic presidential nomination amid coronavirus concerns. The former vice president is on course to expand his lead toward the 1,991 delegates needed to clinch the nomination on the first ballot.
The primaries came as the coronavirus outbreak sent the economy into a tailspin, though large numbers of votes had already been banked in the early voting period.
