Less than 12 hours before voting was set to begin across Ohio, a judge rejected a temporary restraining order supported by Gov. Mike DeWine (R) seeking a delay in that state’s Tuesday primary, declaring that rescheduling the election would “set a terrible precedent.”

Earlier Monday, DeWine had said that no in-person voting would take place in the state’s primary, noting that proceeding as usual would not be in accordance with the Centers for Disease Control and Prevention guidelines against gatherings of 50 people or more amid the coronavirus crisis.

Election officials in the three other states voting Tuesday — Arizona, Florida and Illinois — have said they will proceed with their primaries, though Sen. Bernie Sanders (I-Vt.) questioned the wisdom of that during a post-debate interview Sunday.

Meanwhile, Edison Media Research projected that former vice president Joe Biden had won the Democratic primary in Washington state, which voted last Tuesday.

Following their first one-on-one debate, Sanders and Biden both held virtual events Monday on the eve of more key primaries in a Democratic presidential nominating contest transformed by the escalating coronavirus pandemic.
