Iowa is lean Republican, whether that counts as a Republican state is subjective. It's definitely drawn to Trump as a person, that much is clear.
It's hard to figure what the appeal of Donald Trump is in Iowa... and whether that transfers to Republicans in 2022 or later. The state gave the majority of its votes for Congressional Reps to Democrats in 2018. Iowa is on probation as an R state.
It's not just Trump, FOO supports Kim Reynolds I live right next door to IA, IL, and WI I know the states back and forth
WI will vote for Mandela Barnes due the bridges and roads like in Pittsburgh need badly update and Iowa, likes Reynolds she keeps crime low in the state and balanced budgets
