Larry Sabato’s Crystal Ball: “In Iowa, Rep. Randy Feenstra (R-IA), who got a late endorsement from Donald Trump, lost a gubernatorial primary to Zach Lahn, an anti-establishment newcomer.”“Regardless of who the GOP picked to run against state Auditor Rob Sand, the Democratic nominee for governor, we have been considering moving the race to Toss-up—and we are making that change today.”“We are also bumping both Iowa’s Senate race and the contest for the state’s 2nd District from Likely Republican to Leans Republican.”
