Just based off stereotypes and stuff.
One I can think of is Miami-Dade giving Trump his largest raw vote increase over 2020, while Dane County gave Harris hers (over Biden).
This is fitting because post-2020, Miami was seen as the uniquely Trumpy metro and become symbolic of a new urban right, whereas Dane County has increasingly become this bastion of liberalism that represents the modern Democratic Party on spaces like this forum. There's been multiple posts (pre-election) where I used Miami and Madison as polar opposites to represent Conservative vs Liberal culture, like the post below:
Adding on to what others have said, I think Florida is a state where a lot of the non-seniors who move there are self-selected to be very individualistic, often with superiority complexes.
In the greater Miami area, a lot of the culture is very "show off", "new money", "exclusive parties", ect that just tend to attract more Conservative types. Compare that to say metro Madison which has comparable median income but is just a lot less showy - like if you go on Google Earth and walk around the suburbs, the homes are relatively modest, far fewer people have fancy sports cars and so on.
I think this can also explain why a lot of these people support weird combinations of liberal politics with GOP culture war conspiracy stuff - the individualistic aspect of people feeling above the fray kind of brings them into these weird rabbit-holes "I don't need the vaccine" or "my kids aren't gonna get indoctrinated by public schools"
I guess another result that's fitting is Trump sweeping all the South TX border counties while Harris still clung onto 4 inland counties, given how big of an issue the southern border was this cycle
