Wisconsin voters on Tuesday will elect a single state Supreme Court member in a special election that will determine if the bench keeps its liberal majority. Why it matters: The swing state race is the first major election in the U.

Tuesday’s election to fill a Supreme Court seat in Wisconsin has emerged as the country’s first major political battle since President Donald Trump returned to the White House. It offers both an early test of the president’s popularity in a state he narrowly flipped last year and a gauge of the political machine that Trump ally Elon Musk has deployed to drive up turnout in this swing state.
