Republican strategist Brad Todd likes to say that “Ohio is the new Missouri, and Wisconsin is the new Ohio” to explain how central to winning the White House the Badger State has become since President Trump captured the Midwestern battleground four years ago.

Trump defeated Democrat Hillary Clinton in Wisconsin by a slim 0.7 percentage points, becoming the first Republican to collect the state’s 10 Electoral College votes since Ronald Reagan in 1984. In doing so, the president established Wisconsin as a crucial swing state that demands the constant care of Democratic and Republican contenders alike.
