Thanks for handing us two open House seats!
Hart and Axne both just barely squeaked through this time. After redistricting, winning their Congressional districts will only get harder. If Dems are facing probable defeat anyway, they might as well throw their best candidates into the most consequential races.
Iowa is not winnable at the statewide level for Democrats.
It might be in blue waves (not happening in 2022, obviously) or where federal partisanship isn't in place (c.f. the Democratic row officers there). Reynolds has been one of the better Republican governors so would start out heavily favoured but the downballot is probably going to be pretty competitive in places assuming most incumbents run for reelection.
