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 election board was recently taken over by a conservative majority. Its latest proposals are dangerously late in the process and most likely illegal, according to the secretary of state.

Rules changes approved by the State Elections Board go against the Georgia Constitution, says new lawsuit filed by Republicans.

The once-wonky Georgia State Election Board has burst into the limelight this year as a new Republican majority – made up of a retired obstetrician, a former state senator who put out feelers for a Trump administration job and a right-wing media personality – push ahead with new rules that could create chaos in November.

Georgia election officials have said they are “gravely concerned that dramatic changes” approved by the State Election Board “will disrupt the preparation and training processes already in motion.”
