King, Young win U.S. House seats

Incumbent Steve King cruised to re-election in the U.S. House 4th District race. King, 65, of Kiron, beat out Democrat Jim Mowrer, 28, of Boone.

King, first elected in 2002, has gained a national reputation for his polarizing positions on immigration and social and tea party issues.

He secured a seventh term with 117,020 votes - or 60.8 percent of votes - while Mowrer had 75,168 votes - or 39.1 percent, according to preliminary vote totals.

Mowrer, a political newcomer, is the sixth Democrat to come up short against King. He won his first five terms over little-known and underfinanced candidates and came out ahead of former Iowa first lady Christie Vilsack in 2012.

Meanwhile, David Young edged Staci Appel in the U.S. House 3rd District race, which includes the Des Moines metro area.

He secured the seat with 113,782 votes - or 50.6 percent of votes - while Appel had 99,800 votes - or 44.3 percent, according to final preliminary vote totals.

Appel, 48, of Ackworth, is a former state senator. Originally a financial consultant, she served in the Legislature from 2007 to 2010. She was unopposed in the Democratic primary.

Young, 46, of Van Meter, is a former chief of staff to longtime Republican U.S. Sen. Chuck Grassley. He originally declared his candidacy for Iowa's U.S. Senate race but dropped out of that race to run in the 3rd District. He won a six-person Republican primary that went to a nominating convention.

Appel and Young were competing to replace retiring U.S. Rep. Tom Latham, a Republican.
