Sumter County's race for sheriff featured the Democratic nominee, Tyrone Clark, Sr., and write-in candidate, Thomas Lewis.
The two also faced off in the Democratic Primary this past summer. But Clark took the race Tuesday with 63% of the vote.
Sumter County election officials stayed until the wee hours of the Wednesday morning to count all the votes.
"I just can't thank the voters enough for coming out in support of doing the right thing," said Clark. "Unfortunately, we had this to happen, the write-in thing. But nevertheless, the voters have proven to me that they are upstanding, outstanding citizens and tonight it really showed."
Clark will succeed longtime sheriff, Johnny Hatter, who is retiring.
In Choctaw County, Democratic nominee Lee Henry McGrew, a former chief deputy, faced a challenge from an independent candidate.
Tom Abate defeated McGrew by a 3,505-to-3,318 margin in Tuesday's voting.
About 119 provisional ballots are still outstanding from Nov. 2. Those will be examined Nov. 9, but officials in the probate judge's office said they would not be enough to affect the outcome of the election.
