Voters in at least three rural South Dakota counties are set to decide Tuesday whether to return to counting ballots by hand, the latest communities around the country to consider ditching machine tabulators based on unfounded conspiracy theories stemming from the 2020 presidential election.

The three counties, each with fewer than 6,000 residents, would be among the first in the U.S. to require old-school hand counts, which long ago were replaced by ballot tabulators in most of the country.

A number of other states and local governments have considered banning machine counting since the 2020 election, but most of those efforts have sputtered over concerns of cost, the time it takes to count by hand and the difficulty of hiring more staff to do it.
