I think Iowans are sick of Trump, a Biden win wouldn't shock me.
But I also think Wisconsin will still go to Trump and that Arizona might be a cycle away but it wouldn't shock me if Arizona is won by Biden either. This is all assuming a free and fair election which is a huge question mark at this point.
Blue IA and red WI isn't happenning. If Biden is winning IA, he's doing well enough in rural WI to carry the state. Rs are already pretty maxed out in the WI suburbs, so even if trends stall because of BLM, they aren't gonna be gaining many votes in suburban Milwaukee.
