Protasiewicz, but I think it'll be close.
Ngl, I feel like Protasiewicz made this race a bit too partisan for her own good (though maybe that was unavoidable). She isn't going to be getting any sort of huge crossover support anywhere though.
What this comes down to is who those people in WOW who are voting are. If they're disproportionately college educated and left leaning, Protasiewicz is clearly favored, however, if they're the more old-money conservative types and WOW bounces backa little, this is a tossup.
It's almost universally accepted that democrats lost the race in '19 b/c they took the "above the fray, high-minded legal professional" route and didn't get political enough, which failed miserably at turning out the base. They have learned, and will not make that mistake again.
This. Trying to be above the fray just doesn't work in this day and age. Look at Hillary 2016.
