Incumbent Bill Woolsey beat challenger Trent Kernodle in the Town of James Island's mayoral race Tuesday, according to unofficial results.
Woolsey had 68 percent of the vote and Kernodle had 32 percent.
Woolsey, 58, an economics professor at The Citadel, has served as mayor of the current configuration of the town since 2012. He held the mayor's seat from 2010 to 2011 during a previous incorporation. He also served on Town Council from 2002 to 2004.
Kernodle, 62, is a James Island attorney.
The results will be certified Thursday, said Joe Debney, executive director of Charleston County's Board of Elections and Voter Registration.
"It was pretty much a landslide for me," said Woolsey, who will lead the town for the next four years. He plans to work to reunite the town, provide tax relief, improve law enforcement and build sidewalks.
Kernodle, who was running for public office for the first time, said Woolsey ran a strong campaign to win. He also said he would continue to support the Town of James Island. "I've worked for and with this town for a quarter of a century and I'll do whatever I'm asked to do as long as it doesn't go against my personal beliefs."
The Town of James Island has about 11,500 citizens.
Voters also decided who will fill all four Town Council seats. The winners were: Garrett Milliken, with 19.1 percent of the vote; Leonard Blank, 18.1 percent; Darren Troy Mullinax, 17.6 percent and Joshua Stokes, 17.3 percent.
Six candidates ran for the four seats. The other two were Mary Beth Berry, with 16 percent; and Lyndy Palmer, 11 percent.
Berry, Blank and Mullinax currently hold Town Council seats.
The town incorporated in August 2012. State law required that it hold an election within two years of its incorporation.
James Island incorporated three previous times since the 1990s, but each of those efforts were squashed, largely due to lawsuits from the city of Charleston.
Charleston and James Island town supporters have a long history of being at legal odds. All three previous attempts at incorporation were struck down after the city's challenges went to the S.C. Supreme Court.
After the fourth attempt was passed by voters in April 2012, Riley announced the city would not seek to block it.
One of the strongest legal defenses that allowed the new town to survive was that the current version was drawn to be geographically contiguous. That meant the town had to shrink in size from earlier designs, omitting some neighborhoods such as Riverland Terrace.
