Every election cycle brings at least one or two huge upsets in an Iowa House or Senate race. The most shocking result from a 2016 Iowa legislative race was four-term incumbent State Senator Tom Courtney losing to Thomas Greene in Senate district 44. Like the five other Iowa Senate Democrats who lost their re-election bids that year, Courtney represented constituents who had favored President Barack Obama in 2012 but voted for Donald Trump four years later.
Courtney announced on August 30 that he will try to win his old job back in 2020. He’ll be heavily favored to win the Democratic nomination, but he’ll have at least one competitor in the primary: Rex Troute.
