Another Tuesday, another US primary - but this time the coronavirus threatens to complicate voting

With two key states experiencing outbreaks of Covid-19, both Bernie Sanders and Joe Biden will be hoping for as little disruption as possible, writes Chris Stevenson

Another Tuesday, another slate of states voting over their choice to be the Democratic presidential nominee. While there aren’t anywhere near as many delegates available as on “Super Tuesday” – there is one unknown element, coronavirus.

Of the six states that are voting; Idaho, Michigan, Mississippi and North Dakota are yet to have a case of coronavirus at the time of writing. Michigan, which has the most delegates up for grabs at 125, had 39 tests come back negative, 24 test results pending and 124 people were “under active monitoring” as of Tuesday morning.

It is a state that Bernie Sanders has to win, having beaten Hillary Clinton there in 2016, in order to stop the story becoming overwhelmingly about Joe Biden’s momentum. So I can’t see turnout, particularly among Sanders supporters, being depressed too heavily. It is likely to be the same in the other three states mentioned, even if some people will be worried about entering a crowded polling station and touching voting apparatus likely used by numerous other people.
