SIOUX CITY, Iowa (AP) – Republican Rep. Steve King has won a sixth term in the U.S. House, beating Democrat Christie Vilsack in Iowa’s 4th Congressional District. King had to campaign harder for re-election than in previous years because redistricting lessened the number of registered Republican voters in the district. King also faced a better-known opponent in Vilsack, the wife of former governor and current U.S. Agriculture Department Secretary Tom Vilsack.

King is known for his outspoken conservative positions on everything from immigration to the federal budget. He kept to those positions while campaigning but placed greater emphasis on his family and success as a businessman.

In her campaign, Vilsack emphasized solving problems with less partisanship. She accused King of being more interested in his status as a conservative firebrand than on helping his district.
