Only 40% of over 1.5 million absentee ballots requested had been received by election officials through Wednesday.
And voters who wait until election day will likely face long lines at some precincts, where the voting process will be slowed by social distancing and cleaning requirements. Voting computers will be wiped down to prevent the spread of the coronavirus.
“The COVID threat is still a potential threat to orderly elections and in-person voting,” Raffensperger said.
Raffensperger encouraged voters to be patient, wait for absentee ballots to arrive and then put them in the mail with enough time for them to arrive by election day.
Georgia's deadline for absentee ballots to be received by election officials is 7 p.m. June 9. Voters also have until 7 p.m. on election day to deliver their absentee ballots in drop boxes set up in many counties.
The primary could have record turnout, possibly exceeding 2 million voters. So far, 623,000 voters have submitted absentee ballots and 103,000 people have cast ballots in person at early voting locations.
In the 2016 presidential primary, over 2 million people voted, and more than 1 million voted in the general primary that year. This year's primary combined the presidential and general primaries.
