Although, it's possible there's more brain drain happening from Michigan in general. Living in CO I've met way more Michiganders (and Minnesotans and Wisconsinites) than Iowans. There's probably more disposable income and liberal tendencies that inspires younger people to leave here than Iowans.
There are a lot more Michiganders (and Minnesotans and Wisconsinites) than Iowans overall. I still don't buy that young whites in MI (and NE) voted Biden but those in IA didn't. Not to mention TX/UT/NC, especially as FL/NV go the other way.
CNN has Trump winning the young white vote in Florida by 10 points . I think the CNN white vote by age group makes more sense . I highly doubt Biden won young white voters in any southern states with the exception of Virginia .
Southern white voters are very different from non southern white votes and with the exception of FL and VA which are no where as racially polarized as the rest of the south, every southern state probably would vote to the right of Missouri if it’s racial demographics were like the Midwest .
I get that, but under 30's aren't racially polarized like their parents are, and states like Texas (and North Carolina, somewhat) don't quite have the same dynamics as MS/AR/TN/KY/LA/AL/MS. Like I get young whites in Georgia voting Republican since most of the white population isn't in Atlanta, but in Texas at least, I'd expect similar dynamics with young whites as AZ/CO. Perhaps I overate the percentage of the population in South Lamar, Montrose, and Oak Lawn.
