I expect Trump to open up small yet consistent leads in polling over Biden here in a few weeks, and the state is lean R going into election day. That being said, Biden's numbers have been very impressive given most of us didn't expect IA to be competitive in this election. Biden could win it if he made some visits and put more resources into it, but it's obviously not really worth much investment because the real race will be decided in PA+WI+MI+FL+AZ.
Iowa does have a competitive Senate race, which could go in the Democrats favor if Joe Biden puts some attention into the state.
