We've had ongoing work done by returning officers since last fall. They've periodically engaged with a range of potential.... I believe there are over 23,000 locations that they've been contacting. In some cases, a small number are confident that they can offer their location. In other cases, they simply do not know, and some have said no. There's a range of uncertainty. Of course, that will evolve as the pandemic evolves.
We'll see, but there is ongoing work by returning officers to revisit polling places to make sure that they have a range of options for an election.
