I can't tell if this whole Finkenauer winning in 2022 thing is a joke or not.
Sadly I don't see much of a path for her. Winning her seat back will be very difficult, but winning statewide would probably be even tougher.
Waves always hit the House harder than the Senate. A Senate run is probably her best chance to get back into politics.
Finkenauer will become a perennial candidate if she runs for the Senate in 2022. Her "best", assuming that she won the primary, would be a 7-9% loss against the Republican candidate, if it's an open seat, and a >20% loss against Grassley if he runs for reelection. And that's probably true for
any potential Democratic candidate who runs in 2022, including State Auditor Rob Sand.
