An additional 956 ballots were counted Friday from Clark County Commissioner District 2, and the Republican incumbent, Marc Boldt, extended his lead over third-place finisher Roman Battan.
While Republican David Madore has had the lead since the first results were released Tuesday, Boldt initially was in third place.
Madore and Boldt will advance to the Nov. 6 general election, in which they will run countywide.
District 2 includes most of Vancouver east of Interstate 205, Camas, Washougal and other parts of east county.
In all, 2,815 ballots were counted Friday.
Elections Supervisor Tim Likness said that was more ballots than his staff thought would be counted, as some of the ballots had been challenged.
Likness said there are 777 ballots left to count, about 150 of them from District 2, so nothing will change the outcome of the close commissioner race.
Friday's results showed Madore with a 638-vote lead over Boldt, who had a 314-vote lead over Battan, a Democrat.
Results will be certified Aug. 22.
On Tuesday, Boldt trailed Battan by 37 votes, but the two-term commissioner took the lead after more ballots were counted Wednesday and extended the lead after Thursday's count.
Commissioners serve four-year terms and currently earn $102,228 a year.
Through Friday, a total of 71,459 ballots had been counted, for a voter turnout of 30 percent.
