"This is the most expensive court race in US history, but there's more at stake than just $40m: whoever wins a spot on Wisconsin's Supreme Court could tip the scales on some of America's most pressing issues. The state's top court has the final say on what laws go into effect, and is currently equally split between three liberal and three conservative candidates. The side that wins a majority will determine the fate of key issues including access to abortion and voting rights in the state."
