Unprecedented turnout led to ballot shortages in Wisconsin's largest city Tuesday as voters cast ballots in "historic" numbers to decide a Supreme Court race pitting one candidate backed by President Donald Trump against another aligned with Democrats. The race for control of the court, which became a proxy battle for the nation's political fights, broke records for spending and was poised to be the highest-turnout Wisconsin Supreme Court election ever. Republicans including Trump and the world's wealthiest person, Elon Musk, lined up behind Brad Schimel, a former state attorney general. Democrats including former President Barack Obama and billionaire megadonor George Soros backed Susan Crawford, a Dane County judge who led legal fights to protect union power, abortion rights and to oppose voter ID.
