Longtime Iowa Sen. Tom Harkin’s decision this weekend not to seek a sixth term launched immediate speculation about possible successors from all parties. In this special edition of the On Iowa Politics podcast, the team looks at the early names of who might throw their hat into the ring for one of Iowa’s two U.S. Senate seats.

This week’s podcast features The Gazette’s James Q. Lynch, Quad City Times political reporters Mike Wiser and Ed Tibbetts and Waterloo-Cedar Falls Courier political reporter Jon Ericson. The podcast is produced by The Gazette’s Max Freund with music from Copperhead and Bryce Janey of Marion.
