Kathleen Vinehout, a state senator from rural western Wisconsin, won 8%. (An important source of this uncertainty is that the model uses statistics for the citizen voting age population in each tract, because we don’t know the demographics of the actual Democratic primary voters themselves.) Evers won an estimated 34% of the vote among those under 30. Lesson 4: Whoever wins the 2026 Democratic primary will need to unify a much more fractured party than Evers faced in 2018. His campaign won the 2018 primary by appealing to pluralities of nearly every demographic group.
