One in six absentee ballots returned thus far
As of 20 May, the Montana Secretary of State reports that 355,993 voters — 52.5 percent of the state’s 678,478 registered voters — have been mailed absentee ballots, and that 15.8 percent of the absentee ballots have been returned. As some ballots undoubtedly are in transit via the U.S. Postal Service, the actual return rate is a bit higher.
As displayed in the graphs below, the numbers vary by county.
