The Democratic Party convention is scheduled to be held during the week of 17 August to 20 August in the key state of Wisconsin. Unlike past nominating conventions featuring balloons, confetti and thousands party faithful featured on television, the August event headquartered in Milwaukee, Wisconsin, will be largely held online due to the novel coronavirus crisis.
Although Wisconsin residents traditionally vote for Democratic candidates in presidential elections, they went for Republican candidate Donald Trump in the 2016 election.
President Trump has already announced that he will not attend the Republican National Convention from 24 August to 27 August in Charlotte, North Carolina.
