In a bit. Not 2024, and 2028 would be a long shot in Scott though quite possible in Carver. If not 2028, then Carver should probably have flipped by 2032, with Scott also likely having flipped (though later / by a lot less), or latest by 2036. These counties aren't massively red or anything like posts above might imply, and they have swung decently leftward in the Trump era: Scott was Trump+6.7 (compared to Romney+14.
and Carver was even closer, just Trump+4.9 (it was Romney+19.7)
Both counties are very white, and do not have a lot of college educated voters as well.
This hardly matters. They are still suburban, and even some rural counties that fit the requirements you gave in MN are blue strongholds (see those in far northeast MN, like Cook, which trended hard to the left in 2020 and gave Biden north of 65%, and Lake, I believe Clinton's whitest county in 2016).
Scott County has been relatively stable in how it votes over the past 20 years. If there is a large 3rd party vote share like in 1992/1996 then it could possibly flip
Carver County has been even more stable in how it votes going back to the 1960's.
Not really. Sure, the shift hasn't been as massive as in metro Atlanta or metro Houston, but it's happened, and these counties will pretty soon be within striking distance for the Democrats. And I don't see how Carver's been more stable than Scott...Scott swung 8.1 points leftward from 2012 to 2020; Carver swung 14.8.
