Joe Biden and Bernie Sanders navigated an awkward coronavirus pandemic climate during Wisconsin’s Tuesday primary, the nominating first contest since states across the country instituted shelter-in-place orders.

Official results from the primary will not be known until April 13, due to a U.S. district court ruling that said clerks cannot report results until the deadline for absentee ballots to be received, but the contest is unlikely to change the trajectory of the Democratic presidential race. Biden, who is likely to win the Democratic presidential nomination and has a delegate lead of more than 300, led Sanders by 28 points in a Marquette University poll of likely Wisconsin Democratic voters at the end of the month.
