OKLAHOMA CITY (AP) -- First-time candidate Markwayne Mullin will square off against a two-term state representative from Muskogee in a Republican primary runoff for the 2nd Congressional District seat in eastern Oklahoma.
Mullin finished first in a six-man GOP primary field on Tuesday, but the lead wasn't large enough to win the nomination outright. State Rep. George Faught finished second to force a head-to-head matchup in the Aug. 28 primary runoff election.
The two are vying to replace current U.S. Rep. Dan Boren, the only Democrat in Oklahoma's congressional delegation. Boren surprisingly announced last summer that he wouldn't seek a fifth term in office, and 10 political hopefuls lined up to fill his spot, including six Republicans, three Democrats and one independent.
Mullin had high name recognition because of advertising for his plumbing business.
The winner of this runoff will face the winner of a runoff between Democrats Rob Wallace and Wayne Herriman in the November election.
