Republican Donald Trump lost by nearly 12,000 votes to Democrat Joe Biden.
Wood said he lived in his Buckhead home since 2014 and began spending more time at his South Carolina property over the last three months.
Under Georgia law, voters who move outside the county where they’re registered lose their eligibility to vote if they moved more than 30 days before an election.
Wood voted in the presidential election during in-person early voting on Oct. 14, according to state election records. He didn’t vote in the U.S. Senate runoffs last month.
