Majority control of the Wisconsin Supreme Court will be decided Tuesday in a race that broke records for spending and has become a proxy battle for the nation’s political fights.

Two key races in Florida and another in Wisconsin could provide an early indicator of President Donald Trump’s popularity just weeks into his second term.

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.
