As for recent elections.
Sauk County voted overwhelmingly for Obama in 2008 and 2012, but then flipped for Trump by a mere 109 votes. It's an anomaly.
They also got snookered by Scott Walker in 2010, who won the county by 263 votes. By 2014, a slight Walker fatigue has set in, which snowballed into disgust by 2018.
A fair warning to our president with the emotional development of a 6 year old: You're toast here.
Retiring Guy's prediction: Sauk County voters learn their lesson, abandon Trump.
