This was a Trump+16 seat, Dems did not have a chance here once the incumbent retired.
It’s still hilarious because those are the 'low-propensity Republicans' Abby Finkenauer/(IA) Democrats are counting on to say home in 2022 "without Trump on the ballot" (as if IA's Republican trend totally doesn’t predate Trump or any other R nominee wouldn’t have easily won the state or whatever).
Oh I agree, the "low propensity Republicans" stuff was always a meme, if anything there'll be complacent "low propensity" Democrats who will stay home, because they don't feel a need to vote (this happened to Dems in 2010 and 2014, and happened to the GOP in 2018).
