Tulsa City Councilors Jack Henderson, Jeannie Cue and Blake Ewing successfully defeated challengers to their seats.
The councilors won their districts with large margins.
Incumbent District 7 Councilor Arianna Moore did not fare as well. Challenger Anna America took about 45 percent of the vote, compared to Moore's 28 percent.
America and Moore will face off in the November general election since neither candidate received 51 percent of the vote.
