Arguably the most hotly contested race was for Clay County Commissioner District 2, where incumbent Charlie Brown faced a challenge from Michael Wilkinson.
But Brown maintained a steady 10-percent point lead throughout Tuesday evening, finishing with 907 votes compared to Wilkinson's 726.
"It was very stressful," Brown admitted after all 23 precincts were counted. "But this shows tonight that people understand what we face out there."
Brown added he was looking forward to the campaign heading into the November election.
"(Republican challenger Tony Fenwick) is a really nice guy," Brown said. "He will be a notable opponent."
Fenwick ran unopposed on the Republican ticket, finishing with 2,483 votes.
The Clay County Council At-Large position was another challenging race.
Five Democrats faced each other with three positions available.
In the end, Mike McCullough -- current council president -- along with incumbents Dolores Johnson and Chip Hoskins all earned their way to the November election.
McCullough received the most votes with 1,239, while Johnson finished with 961. Hoskins had 928. In addition, Bill Lovett had 792 votes, while Roger LaPlante tallied 404.
"I felt pretty confident," McCullough said. "I think, in general, people are pretty satisfied with what we've been doing. We've made it through some tough times."
McCullough, Johnson and Hoskins will face Republicans Pat Heffner, John Nicoson and Lisa Rickert in the fall.
There are only three At-Large seats available. Heffner led all Republicans with 2,188 votes, while Nicoson finished with 2,114. Rickert also had 1,749.
In the Republican race for Clay County Coroner, voters believed in incumbent Joel Reinoehl, who finished with 1,878 votes to his challenger, John Fagg, who tallied 914.
"I had a lot of positive feedback," Reinoehl said of the campaign trail. "Everybody was very congenial. I feel like we had a lot of positive feedback."
The only other contested race in Tuesday's Primary, at the county level, was on the Republican side for County Surveyor.
Incumbent John Keller finished with 2,079 votes, while challenger Rustina Johnson tallied 610.
Others heading for more campaigning through the fall include Republicans James Deal (Clay County Circuit Court Judge), Bob Pell (Clay County Superior Court Judge), Vickie Wheeler (Clay County Clerk of the Circuit Court), Bryan Allender (Clay County Commissioner, District 1) and Fenwick (Clay County Commissioner, District 2). All of these candidates ran unopposed in the Primary.
On the Democratic side, other candidates moving on who ran unopposed included Joseph Trout (Clay County Circuit Court Judge), J. Blaine Akers (Clay County Superior Court Judge), Joe Dierdorf (Clay County Recorder), Amy Shelton (Clay County Coroner) and Jack Withers (Clay County Commissioner, District 1).
