US presumptive Democratic presidential nominee Joe Biden has won the primary in the state of Louisiana, according to the media report.

The former Vice President won with 82.2 per cent of the vote, leading Senator Bernie Sanders, who received 5.3 per cent, with 1 per cent of precincts reporting, The Hill news website quoted the New York Times as saying on Saturday.

The win on Saturday comes as he continues to march toward his formal nomination at the Democratic convention in August.

The Louisiana primaries were delayed twice from their original April 4 date, first to June 20 and finally to Saturday, in response to the coronavirus pandemic.

Biden has effectively been his party’s leader since his last challenger in the Democratic primary, Bernie Sanders, ended his campaign in April.

The Democratic National Committee earlier postponed the party’s presidential nominating convention in Milwaukee, Wisconsin, to August 17, the week before the Republican Party’s convention, scheduled for August 24 to 27 in Charlotte, North Carolina.

The DNCC said epidemiologist and infectious disease experts W. Ian Lipking and Larry Brilliant will help advise the committee on efforts to protect the health and safety of convention staff, attendees and Wisconsin residents.

In May, Biden and the Democratic Party raised nearly $81 million, 10 percent more than Trump, although the president has more overall campaign cash.

Biden is currently leading in national polling, as well as in surveys conducted in several swing states like Michigan, Wisconsin and Pennsylvania, battlegrounds that were critical to Trump’s victory in 2016.

The 2020 US presidential election is scheduled for Tuesday, November 3.
