Matt Campbell of Manning emerged out of the Democratic Party primary and will face four-term incumbent Republican Steve King in the Iowa 5th District congressional race this fall.
Votes had not been counted in all 32 counties of Iowa's largest congressional district, but by news deadline Tuesday night, Campbell had received 78 percent of the vote, well ahead of Mike Denklau of Council Bluffs.
The two followed a campaign strategy of talking with western Iowans primarily on economic issues and touted their business experience among their credentials to serve in the U.S. House.
Denklau, 27, worked as a Wall Street banker until moving back to Iowa in 2009 to run for Congress. Campbell, 39, has a background in international tax and merger acquisition consulting.
Campbell placed his campaign headquarters in Sioux City and won the vote in Woodbury County, 1,201 to 290 over Denklau.
Campbell began the important day with a stop in Council Bluffs before journeying to Sioux City to host a results-watching party at local watering hole Buffalo Alice.
King, who lives in Kiron, coasted to wins in 2002, 2004, 2006 and 2008 in the district where Republicans have held a voter registration margin over Democrats of never less than 40,000 people.
"The message is going to be on jobs. We need to grow our way out of this (recessionary) economy, and that is a bipartisan issue," Campbell told the Journal last week.
He said western Iowa has seen stagnant wages during the past decade, so a focus should be on helping small businesses that employ 20 to 50 people. Campbell also wants to help 5th District renewable energy businesses.
