Election: Biden on verge of clinching Democratic nomination

Biden has won 1,556 delegates to date, and needs 425 more to clinch the nomination. In Tuesday’s contests, 500 were up for grabs. On Tuesday, Biden won contests in Pennsylvania, Maryland, Indiana, Rhode Island, New Mexico, Montana and South Dakota. District of Columbia results were pending.

Biden should officially clinch the nomination in the coming weeks; his next chances include contests next week in West Virginia and Georgia, and Kentucky later in the month.

Tuesday’s primaries were a major test for voting by mail, with most balloting done that way as local officials have urged precautions amid the coronavirus pandemic. President Donald Trump is an outspoken opponent of mail-in voting, saying it is susceptible to fraud — despite only rare cases.

The contests in Indiana, Maryland, Pennsylvania and Rhode Island were postponed from April and May. Voters are also casting ballots in Iowa, Montana, New Mexico and South Dakota, in addition to the District of Columbia.

The primaries are being held as the country reels not just from the coronavirus pandemic, but also from violent protests in cities across the nation in reaction to the death of George Floyd. Floyd, a black man, died after he was pinned at the neck for several minutes by a white Minneapolis police officer.

Opinion:State sales tax receipts plunge as much as 41% in April amid coronavirus shutdowns — and May could be worse.

Speaking in Philadelphia on Tuesday, Biden called the death of Floyd in police custody a “wake-up call” for the country, as he blasted Trump over a vow to deploy the military to quell protests in U.S. cities.
