Bernie Sanders wants Wisconsin to put the brakes on the state’s primary set to take place next week.

“People should not be forced to put their lives on the line to vote, which is why 15 states are now following the advice of public health experts and delaying their elections,” Sanders wrote in a statement Wednesday. “We urge Wisconsin to join them. The state should delay Tuesday’s vote, extend early voting and work to move entirely to vote-by-mail.”
