Polk County Clash Ahead As Longtime Legislator Set to Challenge Another Longtime Official

DES MOINES, Iowa  --  After 25 years representing Polk County in the Iowa legislature, Matt McCoy won't run for re-election in 2018.  But he still plans to be on a ballot.

"I am formally announcing my plans to run for Polk County Supervisors, District 5, in the 2018 June Primaries," McCoy told a crowd of supporters on Wednesday afternoon inside Sellers Hardware Store on SW 9th Street in Des Moines.

McCoy's parents owned the store for 30 years.

To win the seat, McCoy will first have to unseat the fellow Democrat who's held it for nearly 30 years.  John Mauro has represented the south side of Des Moines since 1990. Mauro has already said that he would seek re-election.

Mauro is one of the most well-known names in south Des Moines Democratic politics. His brother, Michael, is the former Iowa Secretary of State and current Labor Commissioner. His nephew, Eddie, is running in the 3rd Congressional District.

During his announcement,McCoy did not criticize Mauro.  However, he did use words like "bold", "fresh" and "progressive" to describe what he'll bring to the job.  McCoy says he'll focus on improving mental health services and affordable housing if elected.

McCoy's decision sets off a domino effect in Iowa politics.  New Senate Minority Leader Janet Petersen now has to find a candidate to replace McCoy in the Senate.  There will likely be numerous candidates interested. Progressive activist and Interfaith Alliance Executive Director Connie Ryan announced shortly after McCoy's news conference that she would be running for McCoy's senate seat.

There will likely be an explosive primary battle between Mauro and McCoy between now and June 5th.  McCoy says he'll run a positive campaign.
