Isn't the midwest just saturated MAGA, white Christian nationalist and plain ol' white supremacist? People who vote for centrists but not progressives have long since devoted their lives to the Trump god-king. They don't care about anyone other than themselves, and may turn around because they're personally hurt by the economy. But in that case, they're voting against the incumbent, and don't care who the opposition is, even if it's a proverbial sack of potatoes.
At this point Trump is personally responsible for everyone losing money. At least everyone but the handful of guys getting pardons and government contracts out of him.
Harris lost by playing to the center, and an awful lot of polls are telling us that progressive platform ideas are popular.
