Since 2020s are big yrs for Dems in Senate from 2020-2025, these states are on borrowed time for Rs
IA is not on borrowed time for the GOP, just based on how white it is and the lack of cities it should be Dems who are on borrowed time. WV the GOP will on to for a long time, even if they don't win by crazy 40 point margins. KS will never really be competative, it'll just temporarily get a little more blue because the GOP shot itself in the foot there but soon they'll recover. the midwestern states as a whole the cities are shrinking and rural areas are becoming more R, I can't see MI, WI or OH voting D after 2030s unless there's some big wave year. I suspect PA will remain competative because Philly grounds the state and at worst it becomes Lean R. Honestly, when I was very very new to politics I expected PA to be a safe D state.
I selected IA, because Mike Franken or Greenfield can unseat Ernst and JD Scholten can unseat King. As far as KS, with Kobach winning the primary, Barb Bollier will take this seat
