Tabor Vaux, who won Tuesday's Republican primary for the District 9 Beaufort County Council seat, received broad support throughout the Bluffton-area district.
Preliminary results show Vaux won seven of eight precincts in Tuesday's election, while Mark Lawson won just one.
Overall, Vaux received 529 votes, or 66 percent of the total vote count. Lawson received 296 votes, or 34 percent. Those results, which will be certified Thursday, do not include provisional ballots, which are still being tallied but are not expected to change the outcome.
In all, just 10 percent of eligible voters in District 9 cast ballots in the special election.

No Democrats or petition candidates are running for the seat. If no write-in candidate emerges by Friday, Vaux will win the seat. Should that happen, he would be sworn in Feb. 4.
If a write-in candidate decides to run, the general election would be held March 19.
Vaux, 29, is an attorney with the Bluffton law firm Vaux & Marscher. He is the son of Roberts Vaux, a well-known local attorney.
The seat opened up after fellow Republican Weston Newton resigned last month to join the S.C. House of Representatives.
