Wisconsin was never friendly territory for Trump in a GOP primary. Ted Cruz beat Trump 48 percent to 35 percent (with John Kasich taking 14 percent) in April 2016, after Trump had begun to pull away from the field. If DeSantis can score an early victory end up in a two-man race with Trump, he could likely count on winning Wisconsin down the road.
