Running against a sitting office-holder from your own party is always an uphill battle. Many Iowa House or Senate members have faced primary challengers during the past decade, but only a handful have failed to win their party’s nomination.

Christina Bohannan beat the odds on June 2, taking 66 percent of the vote against 20-year State Representative Vicki Lensing in Iowa’s most Democratic House district.

No one can write off the outcome as a fluke of a low-turnout environment. Statewide turnout set a new record for an Iowa primary, and voter participation in Johnson County was sky-high as well. Unofficial results showed 6,687 residents of House district 85 cast ballots for either Bohannan or Lensing.

Bohannan’s win and in particular the margin of victory should put every Iowa legislator on notice: you have to keep earning your constituents’ support.

A competitive primary is shaping up in the safest Iowa House seat for Democrats. Last week University of Iowa law professor Christina Bohannan announced she will run for House district 85, setting up a race against ten-term State Representative Vicki Lensing.

More Iowa women are running for office in 2018 than ever before, which could lead to record numbers of female state representatives and senators next year.

However, in other meaningful ways, Iowa’s legislature could become less diverse after the November election.
