Where were the biggest Romney-Clinton swings?

[Tekken_Guy]

Where were the biggest swings from Mitt Romney to Hillary Clinton this election. We talk about the voters that Obama lost to Trump, but we don't dissect the part of the coalition Trump lost.

Large sunbelt cities, some wealthy suburbs in the NE and there was an oddly large concentration in the Chicago area.

I never would have thought that Illinois was going to swing Democratic, especially in a Trump win. One of the most surprising results on election day.

I'm not sure that a .05% swing is really a "swing".

Hamilton County, Indiana.  It's usually 65% or so GOP on average, but it ended up being only 57% Trump on Election Day.  Either that was an outlier or the beginning of a "Fairfax County" trend of sorts.
