Republicans nominated State Representative Mark Costello for the December 30 special election to replace Joni Ernst in Iowa Senate district 12. The district covers Mills, Fremont, Montgomery, Page, Taylor, and Ringgold counties in southwest Iowa. This post includes a map.
Seven candidates sought the GOP nomination in this strongly Republican district, containing more than twice as many registered Republicans as Democrats. Besides the five candidates Bleeding Heartland discussed here, David Sieck and Charla Schmid joined the GOP race. Sieck is a Mills County farmer who has been active on Missouri River management issues. Schmid has served several terms on the Montgomery County School Board and is active in Business and Professional Women/Iowa. She also serves on the board of directors of 50/50 in 2020, a bipartisan group encouraging more Iowa women to run for office.
The Iowa Republican’s Craig Robinson wrote up last night’s nominating convention, where Costello led from the beginning and secured the nomination on the fourth ballot.
Earlier this week, Libertarians nominated Don Brantz for the Senate district 12 special. He is “a longtime Mills County supervisor and southwest Iowa social worker” who is running on a platform of increasing funding for rural schools and abolishing the state Department of Education. It’s smart for Libertarians to compete here. Odds are long, but anything can happen in a low-turnout environment, and how many people will show up to vote on December 30?
Costello is the heavy favorite. If he wins, a special election will be needed in Iowa House district 23, covering Mills and Fremont counties, plus most of Montgomery County. House Republican leaders did not assign any committee chairmanship to Costello, perhaps expecting that he would soon leave for the Iowa Senate.
Regardless of who wins the Senate district 12 special, the number of women in the Iowa Senate will drop from ten the past two years to seven for the next two years. First-termer Amy Sinclair will be the only woman in the Iowa Senate GOP caucus.
