With 83-percent of the vote in, Hot Springs Attorney Q. Byrum Hurst conceded the race to Jeffress.
He made the announcement to supporters tonight at about 9:40, telling supporters, "First and foremost, I want to thank my family, friends and neighbors for their tremendous support in this campaign. Now more than ever, it is clear that this district deserves a Democrat committed to building on the track record of Mike Ross, and I am committed to working with State Senator Gene Jeffress to ensure we can Arkansas forward."
Jeffress led the returns all night and with 100-percent of the unofficial results in, had 61-percent of the vote to Hurst's 39-percent.
Jeffress will go on to face Republican Tom Cotton in the November election.
Cotton congratulated Jeffress on his victory in the following statement:
"I congratulate Gene Jeffress on his victory. I look forward to a vigorous and civil campaign focused on solving America's debt crisis, repealing ObamaCare and saving Medicare, and promoting economic growth and job creation through tax and regulatory reform. Arkansans want and deserve a principled debate on these critical issues."
The winner of the race in November fills the seat Rep. Mike Ross leaves after 12 years in Washington.
And with 100-percent of the vote in, Prosecutor Scott Ellington has defeated State Representative Clark Hall in the House District 1 Democratic runoff.
Hall conceded the race shortly after 11 o'clock as returns revealed Ellington's majority.
Ellington had 51-percent of the vote to Hall's 49-percent.
The race went down to the wire as Ellington watched his all-night lead shrink before his win was certain. He made his victory speech shortly before 11:30.
Ellington will go on to face incumbent Republican Rep. Rick Crawford in the November election.
