A whole lot of Iowa campaign news

Laura Belin and Spencer Dirks began with Zach Nunn's bizarre trial balloon, followed by his retreat after speaking to President Donald Trump. They also discussed speculation about Joni Ernst's future plans, Ashley Hinson as a possible Senate candidate, GOP primary challenger Jim Carlin's first digital ad, a slew of endorsements for Randy Feenstra for governor, Mike Bousselot's hint about the governor's race, a prominent Republican's warning about Rob Sand, two Democrats launching campaigns for Congress and two more considering it, and each party's nominee for a special Iowa Senate election coming up in Sioux City.
