Republicans made huge gains in the Iowa House on November 2, defeating 13 Democratic incumbents and winning four Democratic-held open seats. Republicans fell just short in several other House races, and one that puzzled me was in district 7, covering Emmet and Palo Alto Counties and part of Kossuth in north-central Iowa.

Democrat Marcella Frevert retired after representing the district for 14 years in the Iowa House. The district leans a bit Democratic in voter registration, but open seats tend to be harder for parties to hold than districts where they have established incumbents. Clearly district 7 was winnable for the GOP; the certified results put Democrat John Wittneben just 32 votes ahead of Republican Lannie Miller.

For some reason, the Iowa GOP and allied groups didn’t invest nearly as much in Miller’s campaign as in other House Republican candidates. But why?
