The Democrat civil war is real—and it is happening in Wisconsin

Yard signs for democratic socialist Francesca Hong have appeared across rural Wisconsin in recent months. Hong, a single mother and small-business restaurateur, has paired an appealing biography with a platform well to the left of the state’s political center. She has called for abolishing Immigration and Customs Enforcement and establishing universal health care. Now she leads the Democrat field for governor.

Hong’s rise has also thrown Wisconsin Democrats into a panic. Party leaders must either accommodate a socialist insurgency or risk alienating the working-class voters they need in November. The result is a fractured coalition that could puncture Democrat hopes for a national blue wave.

Wisconsin’s primary may reveal the limit of the coming blue wave: Democrats cannot sweep the country while their own coalition is pulling itself apart.
