It was double-digit Republican in 2022, which in Michigan only saw a totally ridiculous Democratic turnout advantage and quasi-landslide conditions. My guess is it remains so safe that it will remain Republican until the current set of trends is replaced by a different set of trends. (Something like this is also my opinion on the state of Kansas -- the Democratic trend there is obviously real, but it's so red that the amount of time necessary for the state to actually flip means that the trend will probably be interrupted by something).
The Democrat in 2022 was a random nobody sacrificial lamb.
