King routinely coasts to re-election victories. His closest call was in 2012 when he edged Democratic challenger Christie Vilsack, 53 percent to 45 percent. Vilsack, the wife of former Gov. Tom Vilsack, entered the race with higher name recognition than other King opponents.
The 4th District, the largest of the state's four congressional districts, covers 39 counties in Northwest and North Central Iowa. Registered Republican voters outnumber Democrats, 190,065 to 119,714.
