One measure, to be voted on Friday, would require hand counting of ballots. Critics say that it would create widespread confusion in a state pivotal to the presidential race.

The state that handed former President Donald Trump one of his narrowest losses four years ago is immersed in election controversies even before the first ballots of this year’s presidential race are cast.

Georgia’s State Election Board is preparing to vote on nearly a dozen rule changes Friday that could take effect before the election, concerning local officials.
