From the esteemed John Deeth’s blog:

While recounts remain possible, incumbent Democrats appear to have won three of the state’s four closest races while losing one seat.

In Woodbury County, Democrats held on to win two tight House races. In Iowa House District 1 incumbent Democrat Wes Whitead had 6,152 votes and Republican Jeremy Taylor won 6,092. At the end of Election Night, Whitead had a six-vote lead. In Iowa House District 2, incumbent Democrat Roger Wendt had 4,709, ahead of Republican Rick Bertrand with 4,429.
