I mean, Iowa is still a swing-y state, especially in wave elections. Remember when Chet Culver lost by 10 in 2010? I have little doubt that Republicans are going to win this (and IA-01/IA-03) back in 2022.
If it's a Democratic midterm, sure, but if Trump is still president, there's a good chance Democrats hold all of those races.
Oh of course, but I don’t think Trump will be president in 2022 if Republicans lose all of those races this year.
Just like how Obama wasn't going to be President anymore because the GOP swept the governor races, US House, and state legislative races in 2010...
