CINCINNATI (AP) – A political newcomer backed by conservative advocacy groups has topped the Republican field running to succeed former House Speaker John Boehner (BAY’-nur) in his GOP-leaning western Ohio district.

Army veteran and businessman Warren Davidson topped two state legislators in a 15-candidate field in both races: for nomination to complete Boehner’s term and for the next Congress. He had 32 percent of the vote with 91 percent of precincts reporting unofficial returns, to 24 percent for state Rep. Tim Derickson and 20 percent for state Sen. Bill Beagle.

“This was a hard fought election and I am deeply grateful for the tremendous support I received from families, small business owners and community leaders across the 8th Congressional District. I congratulate Warren Davidson on his victory tonight,” said Beagle.

Boehner had held the seat since ousting a scandal-marred incumbent in the 1990 GOP primary.

The heavily Republican 8th House district spans six counties containing northern Cincinnati suburbs, working-class cities and long rural stretches. Only one Democrat and one Green Party candidate ran.
